White Screen

[compujas]

All I get when I start the game is a white screen with my username at the bottom and a stripe of clouds across the middle. If I move the mouse around I can find the mode selections and options in the bottom corner. If I click on game option I can see the different options but have no idea what they're set to. Anyone have any ideas, it's pretty much unplayable at this point. It's almost like the contrast/brightness is up way too high but I can't find any option to change it.

Thanks.
