Soldat keeps giving me the Graphics Incompatibility error when I attempt to run it, yet I have the most updated drivers for my ATI Radeon 9800, and DirectX 9.0c.

The game ran fine the first two times I played it. I didn't change anything, and now am getting a graphics incompatibility error.

What would the problem be, and what is the easiest way to correct it?

Make sure that none of your video card settings have changed and that nothing in Soldat's Config.exe has been changed.

If that fails, I suggest reinstalling it, preferably after re-downloading from another location.
