Hi, During a sync, iTunes froze and I had to force quit it. Now when I try to sync, I get an error message saying (rough translation from Swedish): "iTunes could not backup the iPad unit [Device name], because the backup copy was damaged or not compatible with iPad Delete the backup for this iPad and try again" Since then, I have manually deleted the backup (I think?) through Edit->Settings->Devices and manually removed my only backup. That did not work. I then tried to restore sync history from the bottom button on that page, also did not help. Finally, I also tried uninstalling and then re-installing iTunes, but I still get the same error message. I believe this means that iTunes has saved either a backup-file that is damaged, or at least kept a reference to such a file, and that file obviously is NOT removed by wiping backups through iTunes nor by re-installing iTunes. What am I supposed to do now? Is there any way to manually fix this by removing some file(s), and if so, which files/from where? Formatting my computer is not an option, this has to be fixed somehow. I am running Windows7. Thanks in advance!
