Hi, This week my new iMac arrived. I transferred my itunes library off of my pc to my mac using senuti. I then reformatted my ipod to use on a mac and copied my music onto it. But nw when ever I try to update it i get this error Could someone please help me. I have no idead what to do. I've looked through the apple support site, done the 'r's and also used senuti for a second time. I hope it's not a had ware problem cos my ipod warranty only ran out a month ago.
