Unable to recover old backup

I have been using Norton backup for over a year into a separate hard disk but never tried to restore at all.  Lately I upgraded my operating system to windows 7 and reinstalled Norton Security suite.  When I attempted to restore my old backup, I was not able to see the backup set.  I tried to use arestore.exe and arestore.loc on the backup hard drive and unfortunately the newly installed Norton created a new arestore.loc and only shows the recent files (i.e., a backup set after the new install)  the old backup sets are still there but I am not able to read them.

 

Is there a way to recover them?  Any help is appreciated.

I never had a problem using newer versions of the arestore files.

Are the old backups in the same location as they always have been?

Both the old backups and new backups are currently all in the same folder?
