Clearing Recovery Point Sets

I am trying to define a new backup, after deleting all previous backups. I have even reformatted the backup drive after deleting the backups from within Norton Ghost 15. Basically trying to take it back to the beginning, as it was before ever doing a backup. In the Define New Backup, it tells me I can only do a One Time Backup, not a Recovery Point Set, because my drive is already defined in another Recovery Point Set, and can only be in one. But I have deleted all Recovery Point Set backups, and deleted all defined backup job descriptions. How do I tell the program the drive is no longer part of any Recovery Point Set? Thanks! Jon
