Answer 1

that happened to me once. you can either sync it or restore it.

Answer 2

If your iPod has been erased or "restored", you should still be able to re-synchronize it with your current iTunes library. All you  must do is connect you iPod to your computer, be sure that it shows up as a peripheral in the iTunes window (and/or on the computer desktop, My Computer window, and any other locations in which external devices are displayed), and click the "Sync" button.

If you wish to restore songs from your iPod back onto your computer, you may use a simple piece of software titled Senuti (Macintosh is required).

It can be found here: http://www.fadingred.org/senuti/

Everything mentioned above is available for free, granted that you already own an iPod which is formatted to operate compatibly with your current Operating System.
