Screen Resolution Issue

[Totenkopf]

I am having a problem with the screen resolution after the initial install game is complete (i.e. when I start up the game for the second and subsequent time).

I receive a vary 'colorful' screen display whether it is the menu display or the game itself.

I am currently using VISTA and my graphics card is a Radeon X1300. For about a week, it seem to be working fine. And, as I mentioned previously, the first time you start the game after 're-installing' it, the graphics are fine.

Can anyone help?

Thank you
