I just found my old DMB v8 edition and it gives an Invalid Argument was encountered when I click on Scoresheet either in the middle of a game or at the end. Force qutting via the Task Manager is the only way out.
I know this is an old version, but is there any patch available for it to fix this issue.
If not, I guess it's time to upgrade to the latest version.
DMB's support for version 8 ended many years ago. The software itself has not been updated in over 15 years and is not fully compatible with any version of Windows newer than Windows XP.
If you would like to upgrade, Diamond Mind offers owners of a previous version of Diamond Mind Baseball a $5 discount when buying the latest version of the game. You can request a discount code by contacting DMB support.
