Stuck on "Restoring iPod software..." for 5 hours - help!

I just got both the macbook and the ipod touch. everything was working fine, but after downloading 2.0 software for the touch, the process has stalled at the box that says "Restoring iPod software..." The bar has moved once and only by a small amount, and it has been at least five hours or more!

How long does this normally take and what can i do to fix it???

Thank you in advance!
