I have been able to sync my iPad fine before, just barely I tried two times and both times it came up with this. First when I plugged in it said: "iTunes was unable to load data class information from Sync Services. Re-connect or try again later." So I pressed ok, it actually synced and all but then after it said: "iTunes could not back up the iPad "Ben Hollberg's iPad" because the back up session failed." Then I pressed ok and it just looked normal in iTunes. I tried to back up manually by right clicking on the device in the iTunes sidebar but the same message came up. I have now tried syncing three times and this has happened every time. Any help would be great. Thanks.
