Nero Restore problem

I made all my backups on Nero Ultra 7, worked great.
After having some problems with my Win XP pro I had to reformat my HD.
Now my Win XP Pro issues are over.
I installed Nero 8 when I reinstalled my software having the problem of getting a system error 1307 when trying to restore my backups. I uninstalled Nero 8 and reinstalled Nero 7. But the problem persists. Restore says “Restoration complete” but nothing gets restored it gives a message of lack of ownership of the object.

How can I solve this issue?

Thanks for your time!
