I have played this game for almost 100 hours on steam with no technical problems. I upgraded windows to 20004 version and now I keep getting "Sorry, a critical error has occurred and the program will terminate" I checked the these forums and for non steam players, the 1.04 beta patch seemed to fix what appears to be a similar problem Any suggestions as to what I can do with a steam version? As some have mentioned in these forums the steam 1.03.1 patch seems more recent that the 1.04 beta patch. I have tried validating the files, and reinstalling but the problem persists. I am not the sharpest knife in the cabinet re tweaking these games so I apologize in advance.
