Need help restoring exchange mailbox folder...first time doing it

I am running netbackup 7.5 on linux and need to restore an exchange email folder from a backup...here are the steps I have taken thus far.

Used BAR to select what needs to be restored, started restore, found I need to move the backup from tape to disk.

Duplicated the data from tape to disk.

Now I cannot get the data that is on disk to become to primary so when I try the restore it fails because it is reading from tape which it cannot do.

When I go to the catalog and search for the backup id to promote to primary I get the following error:

INF - Skipping backup id xxx123.xxxccvv.org_1326858639001, copy 1 is expired.

Please help me. :(
