AO, am I right in thinking that you didn't have to save the music to a separate medium but chose to do so for safety?
The reason I ask is that when I try to upgrade to the latest version of iTunes on the home PC, it tells me that it can't upgrade because the current version on the PC was not installed properly and that I should do what you did ie uninstall and reinstall. But I guess we will lose all the playlists etc within the current installation, but the newly reinstalled version should go looking for your music files within Windows (still Xp in my case) and take it all into the Library for you (me) to then reorganise into playlists etc?
Can anyone confirm/contradict?
