So I've had this problem for a while. I've tried reinstalling it, deleting it completely and reinstalling it, changing the settings, and a whole bunch of other "solutions" but it never works. I have Windows XP and I've heard that it could be that. I did a check a few minutes ago and it said it was an incompatible application. Could that be because of Itunes 10? Whenever I turn on the computer it says that an application has messed with the color scheme or something and it says it goes to a default color scheme. Can someone please help me? I've also tried the safe mode and it still doesn't show up. It acts like it'll open, like showing the loading circle by the mouse, but it doesn't.
