shortly after upgrading to 3.0, my music wont sync to my ipod touch. it will go through the process of syncing and it acts as if it is loading all my songs onto my my ipod, but then at the end of the syncing process i get an error (13001) and it tells me there is a syncing error. when i look at the settings, it shows that my ipod has stored all the songs, because there is 14 Gb of data, but my music just says no content. i have reset the ipod, reset settings, restored the ipod, deleted and re-downloaded itunes, and im wondering if i just need to downgrade back to the lastest 2.x.x version. please help!
