I tried to play a game mod for a classic old game Diablo. I can play the game without problems on my i7, 6 GB RAM, Windows 7 x64 computer but when I run the mod in question I get this error:
I asked about it on the game mod's forums and it was suggested to me to run one of those "PC spead up/registry fixing" programs but I don't think that's a good idea. The game mod in question runs on my other computer and this one is fine otherwise, everything works as it should. How can I troubleshoot the problem in question and fix it?
