Hi there and welcome
Are you getting this error on the actual screen of the iPod or on your computer when you try to synch it?
Please let me know
ok, download itunes on your computer from www.itunes.com
Then connect the iPod to the computer, and hold the home and power buttons until iTunes says it has detected a device in recovery mode
Then release and choose to recover the iPod within iTunes.
Tell me what then happens please.
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
