Question : Database is locked

I'm getting an error message with Norton Ghost 12 and this is the second time the error appears again. The error  occured when Ghost want to run My Documents backup. My Computer backup just run normally.

The error is:
---------------------------------------------------------------------------------------------------------------------------------
An interaction with the catalog's database layer failed unexpectedly: sqlite3_step--5: database is locked.

Error E4BC0012: An interaction with the catalog's database layer failed unexpectedly: sqlite3_step--5: database is locked.
---------------------------------------------------------------------------------------------------------------------------------

Or see the screenshot:

The first error comes when I 'Run backup now' in the Easy Setup wizard after installing Ghost for the first time.
The second error comes when Ghost want to run its missed backup (I click 'Yes' when the Ghost ask about missed backup).

Someone know how to fix it? Sorry for my bad english.

Here is the information posted:

Ok, with the help of support, I have this figured out.
The problem is that there's at index file that GET corrupted. All you have tons of DO is DELETE the index file.
Support says it doesn't really net curtain any useful information?? Sound wierd, why have the file?
Either way,

Stop the Norton save and Restore service,
Go to C:\Documents and Settings\All users \ Application DATA \ Symantec \ FileBackup and DELETE the Catalog.dat file.
Restart the service, run your backup.
