Game crashes with CEM enabled.

[Brainless]

I have weird problem. I can not complete any mission with CEM enabled.
When CEM is off, I don't have any problems. But when CEM is enabled, game always crashes, video card freezes, and I need to reset my computer.
Sometimes crashes after 5 seconds in mission, sometimes after couple of minutes.
Also It is strange, that if I let the AI to play (turn autopilot on), the game don't crashes.
I know that my video is not powerful enough, but I can play with CEM off.
