I installed the Z patch over my Y version and now my game says I'm a Demo Racer. The readme for the Z patch says that it isn't compatable with the Y version. The instructions for the Z patch tell you how to go from Y to Z. I don't understand! Why give instructions to patch the game with the Z when it's not compatable with the Y??? Anyway, my game is ALL screwed up and I need to install it again. What is the best way to go about this? I have 3 unlocks available.
