I am getting the same thing. Random freezes which causes the game to stop responding. And i have a Intel Quad core 3.0, 8-Gigs of RAM, G-Force 280 (NVIDIA) and Windows Vista.

The game runs with no effort whatsoever is just after a while it will permanently freeze and I have to go into the task bar manager to end its task. I have looked everywhere for a solution to this problem and have not found one.

Can anyone point me on the right direction?
