Constant Crashes

[Darkz]

i'm having constant crashes too.
It happened twice while direct controlling infantry to trow a granade.
And some other times doing random stuff. but always while direct controlling.

This are my computer specs
Intel Core 2 duo E7400
4gb ddr2 1066
Windows 7 ultimate. fresh fully updated install.
Nvidia 8800GTS

---Edit.
this is the error message that shows when crashing.
This time was when the game was loading. On a ranked game.
This is the third time that the game crashes on ranked games and now i have 3 early exits.



---Edit 2
This error happened twice today.
