Can't create new Ghost 14 recovery point set

With Ghost 14, I'm trying to create a new recovery point set for my P: drive.  However, the option is grayed out and I have the message "The recovery point set option is disabled because you have already assigned a selected drive to an existing recovery point set backup job.  you can only have one recovery point set defined for each drive."

 

This P: drive is the same partition that used to have a different drive letter and different volume name.  I removed the job for that archaic volume name from within the Run or Manage Backups window.  I also deleted all the backup files from within the Manage Backup Destination window.  

 

Evidently, this wasn't enough.  

 

I searched C:\Documents and Settings\All Users\Application Data\Symantec\Norton Ghost .pqh files having the archaic volume name.  I found one that could have been second generation archaic.  That is, a name prior to the most recent prior name.  I hid that file by renaming X.pqh to ---X.pqh---.  This was still not enough.

 

I also rebooted once or twice between steps.

 

How do I make this sucker forget about the old backup job, WITHOUT having to uninstall and reinstall Ghost, and set up all my many complicated backup jobs again?

 

Thanks!
