Hey everyone, I've tried looking online and I can't seem to find the correct answer I need to solve this problem. I recently bought a Mac Book pro, a couple weeks ago, and everything was working fine in iTunes, but then one day I connected my iTouch and it asked to update so I did it. After that update, whenever I connect my iPod, it says "the ipod cannot be synced, an unknown error occured.(13014)" Every time a song is finished playing and goes on to the next one, the error message shows each time. I tried going to preferences and checking the box that says prevent ipod from syncing, but it still didn't work. I have a 160GB ipod, with the latest itunes. I've also tried uninstalling itunes to a previous version but when I did that it said my ipod wouldn't work because it was updated with the latest iTunes. I can upload music fine from my itunes library onto my ipod, but as soon as its all loaded into my iPod, the sync message comes up. I'm just confused why it keeps popping up when everything else is fine. Any help would be great!
