I\'m wondering if you lost everything because you hooked up to a different itunes than your home and sync\'d up with that version. If that version of iTunes didn\'t have all the music on it that yours did and you sync\'d you will lose everything. All of your files should still be on your computer as long as you didn\'t delete them from the iTunes file on your computer. Try and go onto your CPU and sync up and see if you get anywhere with that. Wost case scenerio, the actual files are in a file folder with weird names. If you have the time, you can listen and re-key all the tunes, but that\'s a lot of work.
