I am on Windows 7. Yesterday I ran an iTunes update and today I receive this message when I try to launch iTunes: This copy of iTunes is corrupted and not installed correctly. Please re-install iTunes. I am woried that I have already lost my music and don't want to re-install.

I found this on another discussion board and it really helped, I didn't have to uninstall anything and didn't lose any music
Restart the PC. If you're using Vista or 7, now head into your Uninstall a program control panel, select "iTunes" and then click "Repair".
