graphics problems in winspmbt

[interstaterunner]

Hey guys, I am having a problem with my winspmbt. I have played it several times since downloading and everything was fine. However, it has recently began to have graphics problems. The colors go askew. everywhere except for the info bar at the bottom of the screen. All the button and icon shapes are intact, just the colors seem to be hilighted. Almost like a 16 bit color system is trying to run a 32 bit program. I set my saved games aside in a separate file and re-installed the game but the problem persists. Any help is greatly appreciated. Thx guys.
