Any suggestions as to what to try when the instructions at http://support.apple.com/kb/TS1372?viewlocale=en_US&locale=en_US haven't worked?
I had to view the ipod in my computer, right click, select format. This wipes the ipod, but so does a restore through itunes. When i opened itunes again it said welcome to your new ipod and let me sync again
