Got a message of "Main executable for Mental Omega has stopped working" while playing the first campaign of soviet. The timing of CTD is random.
Using WIn7 64bit system. Both happen in windowed mode and full screen with 1920X1080 and 1600X900 screen resolution.
9/7 edit: After turning off both FRAPS and AMD game evolved, the problem no longer exist. Hopes the information help.
