Where are the tracks? Where does iTunes think they are? Use CTRL+I to Get Info. on a broken track, say No when prompted to locate and look at the summary tab. The location will begin file://localhost. Now find out where the file really is, just search for the filename & extension, e.g. 01 Help!.mp3
It may be possible to move a section of folders to where iTunes expects to find them, or correct a preference file if the difference between paths is an additional \Music folder. Alternatively, I have a script called FindTracks that may be able to relink the media if pointed at the folder where the files are stored.
