Thanks I did the DxDiag and it indicated there were no issues . I saved all 5 tabs. Tried to attach but got a message in red "The extension txt is not allowed. "

I can play the original version but when I update to new version ...

Thanks but that did not work. I then deleted all my saved games and reloaded the program. That worked but I realized I had older version when I started a campaign. So I Then updated to most recent version but then I again began getting the error message so I am back to square one.

I can not open Play Order of Battle - I get an error message ....
