Has anyone been experiencing problems with the most recent update?

I have a Ipod Classic 160GB so you all know. Anyways it said today that it needed to be restored which I did that, but then it was unable to sync my music and now everytime I attempt to sync my music I get a message from windows asking if I would like to scan the disk (iPod) which it recommends. When I click on yes scan and fix windows and iTunes freezes and if I ignore the message from windows iTunes freezes anyways. I completely reinstalled iTunes after this originally happened, but the problem continues to persist.
