Solution:
- Make a full reset (with full memory cleaning) of your PPC as described in Uninstallation section.
- Retry the Restore operation but do not reset your PPC even the Windows CE ask you.
- Run the ArtSKey right after end of the Restore operation but before resetting your PPC. After some actions the ArtSKey will ask you to reset your PPC. Do it now using a reset button.
