My dad just got his iPod nano. He wanted me to set it up, so I did. Now, after I complete the setup, it says there is an update, so I update it. After a while, it seems that iTunes wasn't responding or the update was having issues. The loading bar didn't move an inch. I reset my Mac, loaded iTunes, then had to restore the iPod since it was unplugged during sync. So now I'm sitting here and the loading bar hasn't moved a single inch in the past 20 minutes. What is wrong? If someone can help, please reply. Thank you.
