Frequently Asked Questions

General Questions

How do I place an order?

The entire catalog of Diamond Mind software products and pricing can be viewed online at our website and all order and payment processing is handled automatically by our online store. Once your order is completed, your files will be delivered via download links sent to the email address used to place your order.

To get started, browse through the site until you find an item that you wish to buy.

From the product page for the item, Click the "Add to Cart" button. This will add the item to your order and display your Shopping Cart. From here you can click the "Check Out" button to proceed to enter your customer and payment information or click "Continue Shopping" to add more items.

As you complete each step of the checkout process, the display will change and move you to the next step until, finally, you are prompted to complete your order.

When your order has been confirmed and processed, a confirmation web page will be displayed with instructions on how to download your file(s). This information will also be emailed to you shortly after your order is completed.

Is my account information secure?

We are committed to protecting your privacy. Diamond Mind Baseball does not sell, trade or rent your personal information to others.

Your credit card information is safely processed on our site. During the checkout process, you will notice the small lock icon located in the address bar of your browser. This represents that you are on a secure page. We take additional precaution by not storing your payment information on our servers.

How will my order be delivered?

When you make a purchase from the Diamond Mind website, you are offered the opportunity to download your file(s) immediately from the order completion page. You are also sent an email shortly after your order has been completed (usually within 30 minutes). The link(s) to download your file(s) can be found in that email. We do not offer delivery on any physical media such as CD or DVD at this time.

How do I get a refund?

We believe Diamond Mind is the most statistically-realistic baseball simulation, and we stand by our products. However, because there is no way to "return" digital products such as downloaded software, any refunds are on the honor system. For that reason, we now offer a 30-day money-back guarantee on the Diamond Mind Baseball Game software only. This guarantee DOES NOT apply to season databases and other companion products.

What if I need to replace a file?

The download links associated with an order from the Diamond Mind website are not meant to be permanent nor are they unlimited. Every download link is unique for each order and once generated allows for a one-time download with some leeway added in case of potential browser issues or download errors. 

If additional downloads are required, we offer replacement files for the discounted price of $3 upon request. However, it should not usually be necessary to download your Diamond Mind files more than once since no registration or activation code has ever been required to use any of our software and there is no limit on the number of times you can use your original installation files to install the game or any of your seasons for your personal use. This allows you to easily make backup copies of all your Diamond Mind software and copy your files between computers using many different methods including a portable hard drive, USB memory stick, or an online file storage service, such as Dropbox or OneDrive.

To protect your investment and to avoid replacement charges, please be sure to make a backup of all of your Diamond Mind software as soon as possible after downloading your files.

If you cannot find your original game or database installation files and you do not have a backup, you can contact us at to request replacement files.

How can I view my order history?

Due to a number of changes to Diamond Mind's online store over the years, a complete customer order history from before 2015 is not available for viewing online from our website. However, we do maintain an offline database for reference that includes the customer records from all previous iterations of the online store as well as all orders placed directly by phone, email and the old mail-order forms from the earliest years of business. 

You can view the details of your most recent orders (since 2015) on the Order History page by signing in to your account on the Diamond Mind website. Click on the Account icon near the top right of the Diamond Mind website and then enter your email and password when prompted.

Once you have successfully logged in, click the My orders button to view your order history. You can click on an order number to view the details of a specific order.

How do I change the email associated with my account?

We are happy to make this change for you if you send us a message mentioning your old email and your new email.

Do you offer discounts for large orders?

We offer a 10% discount for orders over $100, a 20% discount on orders over $200, and a 30% discount on orders over $300. These discounts cannot be combined with any other discounts or coupon codes.

These discounts apply to products for use by a single customer. They do not apply to orders covering more than one person. For example, a league commissioner cannot earn a 30% discount by placing an order for 24 copies of the current Season Disk for league members.

Please contact us at before placing your order to request a discount code or check out this information page to view the codes for the various discount levels.

How do I use a gift card or discount code?

Discount codes can be entered in the "Gift card or discount code" box on the checkout page. Be sure to click the "Apply" button to update your order total before moving on to select your payment method.

Please note:  Discounts cannot be combined and our online store can only accept one discount code per order. To order multiple discounted items you can create multiple orders using the appropriate code for each one.

Is there a downloadable demo version of the game?

Sorry, we don't have a demo version available. We strongly suggest that you review all of the information available in our About the Game section for details on Diamond Mind Baseball

Can I play DMB on my Mac computer, Chromebook, iPad or other tablet?

All Diamond Mind software is currently supported only on the Windows operating system. To be able to use the game software and any companion databases, you need to be able to download and install the game on a computer that is running Windows Home or Pro editions.

We do not currently offer a version of our software that is compatible with Mac OS, Chromebook, iPad or any other non-Windows tablet or device.

What are the system requirements?

By today's standards, the system requirements are quite modest. DMB runs on Windows-compatible computers that are equipped as follows: 

  • Windows 10 / 8 / 7 Home and Professional editions (32-bit or 64-bit).
  • 800 x 600 or higher resolution 
  • 30 MB of hard disk space plus a minimum of 2-3 MB for each season disk, which includes the space needed for full year-to-date statistics for all teams and players. You may need as much as 40 MB for a season disk if you turn on all of the options to save game-by-game stats, boxscores, scoresheets, and game logs. An additional 75 MB may be needed if you choose to generate a website containing all possible reports for a large league. 
  • an active account with an Internet Service Provider (optional, needed only if you want to use the NetPlay feature to play head-to-head over the internet)
What if I need help with a product I purchased from you?

We are happy to provide free ordering and technical support by email to all of our customers. We do our best to reply to all messages within 24-48 hours during regular business hours (M-F).

You can contact us by using the Contact DMB link found near the bottom right of our website or by sending an email to one of the following email addresses:

For general inquiries:

For technical support: 

We understand that email may not be the preferred way of receiving support for some people, but it is the most efficient method for us to communicate with the greatest number of customers.

Since we do not offer technical support over the phone, we do not maintain a phone line with which to contact customers. This helps keep our costs down so that we may offer you better value for your money.

Technical Questions

How do I download my files?

After your order has been completed, you will be sent an email with the subject "Your Diamond Mind Baseball downloads are ready". This email will contain the links you can use to download your files.

Once you have received your downloads email, you can either click the links or copy and paste the URLs into your web browser to open the download page for each item.

From the download page, click the "Download Now" button.  Depending on your web browser settings, the browser should either start the download immediately or ask where you would like to save the file.  If prompted, choose where to save your file on your computer.  The usual location for files saved from the Internet is the Downloads folder.

How do I copy my databases from a previous version?

If you are using Diamond Mind Baseball version 12 and you also have an earlier version of DMB (version 8 or newer) installed on the same computer, you may want to copy some of your existing databases into the new format.

When you want to convert a database to the latest version of DMB while also maintaining a copy of the database in the old format, the File -> Copy database command is the best choice.

You can find step-by-step instructions in Diamond Mind's built-in help library or on the Diamond Mind website.

To access the instructions in the game's help library, click Help on the main menu bar and then click Help Topics. From the help contents, double-click "Managing DMB Databases" and then click "Copying a database".

Or you can view the following instructions page on our website.

We suggest that you get started with the tutorials that are included in the game's extensive built-in help library to familiarize yourself with DMB's features and how the game works. To access these tutorials click Help on the game's main menu bar and then click Help Topics. From the Help contents, double-click the "Tutorials" topic heading and then click on the "Tutorials Overview" subtopic.

Also check out the Helpful resources for newcomers topic on the Diamond Mind Baseball support forums.

Am I able to use my old season databases with a new version?

Yes. We have always had the commitment to maintain your investment in season disks purchased from Diamond Mind. Every new version of the game includes a feature that converts season disks from older formats to the format used by the new version.

For version 12, any season disks that are in version 8 or newer format are automatically converted to the format used for version 12 when you first install them.

NOTE: If you have season databases in formats older than version 8, one option is to use your earlier version of DMB to convert them to version 8 first, then use version 12 to convert them the rest of the way.

We periodically upgrade our older season disks to add new players, add new statistics, add real-life transactions and lineups, and take advantage of new game features. If you own older seasons, you may be eligible for discounted upgrades to those seasons. See Season Disk Upgrades for details.

What park images are available? Will you be doing park images for old-time stadiums?

Version 12 includes scale diagrams for all of the parks that have been used since 1972 and a sampling of parks from prior to 1972. We plan to continue adding diagrams for older parks. New park images are made available for free download via our Ballpark Images page.
