This happens also in single player mode so I know it's not due to the added load of multi gameplay
In space missions everything is just fine until I jump into any star fighter. Note that as long as I walk around in the hanger everything is fine. But as soon as I take off and fly out into space the screen locks up and I have to restart the computer.
If anyone knows whats wrong I would be grateful for some advice. I'm fine guarding our hangers, but sometimes I just want to fly

I have the actual game discs that I use to use, and I bought the steam version hoping that would fix it, but no


If it's needed here are the specs on my super box:
Intel Core2 Duo 2.67 GHz
4GB RAM
GeForce GTX 260
Running Windows 7 (64 bit)
