Hi! I will install Windows 7 on my PC in the next few days, but I don't want iTunes to say "This iPod is synced with another iTunes library - format or don't sync?" when I connect my iPod to the new Windows. Is there a way to backup the iTunes library and import it again so that iTunes doesn't create a new library and won't make problems with syncing my iPod? I don't want all my apps to be re-installed and stuff!
