ATI 2013 with Plus Pack Installed on Win XP-Pro - Backuplist of Configured Backups is empty after validate

Hello Community,

I have a very strange Problem with my ATI 2013 with installed PlusPack both in latest version on a fully patched Windows XP Pro.
After a validate of the Backups all configured Backups vanished in the Backup List.
There is no chance to get them back. Also the search for Backups did not solve my Problem.
What I did is an unistall of the Plus Pack. After that I unistalled ATI 2013 complete.
After a reboot I reinstalled an activated ATI 2013 without PP and all my configured backups have been automatically discovered and are back in the list. !!! I was happy so far ...
After re-installing and activating the PlusPack again the Backuplist of the configured Backups was blank again, and there is no chance to get them back.

The last thing I tried is de-installing the PlusPack once more and started ATI without a reboot and my backup list is back again, but the Pluspack is de-installed now ...

Does anybody in the community have the same problem, or is there a patch or a workaround from the acronis specialists for my Problem?

Thanks for your help
