Restore Data backedup through NTbackup

Hi Experts,

I need to restore data from tape being backed up thru WindowsNT.I had tried the following steps 

1.Inventory the tape in Backupexec 2012-Successfull

Upon inventory the tape shows as Retired Media

2.Catalog the tape-Fails

The catalog job runs forever untill cancelled

The tape drive picks and leaves the tape 

Is there any technote for Backupexec 2012 which shows how to restore data backedup in other environment and other backup software

Thanks in advance.
