Pink screens in two of 4 races in NFS: Porsche Unleashed

[fletcherdd]

I am using the latest ASUS 5.22 drivers for my ASUS 6800 DDR so the game actually runs now but when I try to play the 1st and 3rd racetrack everything is pink and washed out except for the background images(like the mountains). Does anyone have any ideas? The other 2 racetracks are perfect. Very strange problem don't you think?
