Graphics problems with Call of Duty demo

I just downloaded the demo for Call of Duty and it installed and runs except for the fact that all the menu options are white and i cannot read them. And when i start a mission all the textures are non existant. The character models and buildings are all white. It seems that only the 2d graphics have any color to them and all the 3d graphics are missing the textures. I have a radeon 9800 with the lastest drivers, and updated directx 9.0b patch for windows xp. Can anyone help me in fixing this problem?
