Backup-Restore does not work properly

[Hammer459]

Using mintBackup to backup my user on Mint 13 (Maya)
Installing Mint 14 (Nadia) (on a new disk) and try to restore my user files with mintBackup.
At backup time I specify backing up /home/<my user>
At restore time I specify restoring to /home/<my user>
All files end up under /root. This means I can not upgrade from Maya to Nadia
