iPod sync error - 13014

This problem started yesterday - out of absolutely nowhere! I plugged in my ipod to play on my Macbook Air and this error keeps popping up about every 15-30 seconds. Needless to say it's irritating and interrupts everything else I'm doing on my computer.

"The iPod (Liia's iPod) cannot be synced. An unknown error occurred (13014)."

Now I've never tried to sync it, I think it's referring to the initial sync when you plug it in, but anyway I've gone through absolutely everything I can find mentioend on forums, here in Apple help, asked everybody I know with an ipod and absolutely nothing has helped.

I'm using an iPod Classic 120GB, I've had it for about 3 years and this is the first issue I've had with it. Being that I've had it for 3 years I REALLY don't want to restore the ipod because it's got a lot of music on there.

Can anybody out there help me? I have no idea what to do.
