My gf plugged her external with itunes on it into my Win7 machine and messed around with her music. The next time she tried to open it it gave her an error saying the folder path 'My Music' contains an invalid character. I am now unable to install or uninstall itunes because once that error pops up the program crashes. It looks like there used to be a Microsoft utility that could fix this but it has been taken off of their website. Anyone know where I can get this program or of another way to fix the problem?
