game glitch?

I have a problem with CFS3. It tends to quit by itself when I either start a new campaign, press F1 or overwrite my save file.

I went to Microsoft's help page, but that didn't solve much either. I tried re-installing it, but that didn't help either. My system specs are:

WinXP Media Center 2005
P4 3,0GHz
512MB
GeForce 6200

Make sure you have the latest DirectX and I see your using an older video card, don't use the latest drivers roll back a few.

I hope you have the patch.
