My mouse turns Black too but the sim still works, you mean to tell me that microsoft says fs9 will not work with vista??????? Don't worry we'll figure something out. How far into the repaint were you when this happened? is it still in tact? I am sure we will find a solution to your fs9 problem, you didn't answer my question, when you reinstalled fs9 did you start it before you installed any add ons to be sure it worked? also have you installed fs9.1 patch?
