Trying to Restore MS Exchange First Storage Group

[CAHRD]

If I wanted to restore a mailbox how would I do this?
I have the right Application agent to backup Microsoft Exchange. I have it checked as a selection on the backup.
First Storage Group size shows 1 bytes (which seems very small, Is this backing up properly??). I've tried to move the restore but I get the " could not be moved successfully" error.
I don't want to run the whole restore back on the server.

Any suggestions? I have Data PRotector Express 4 Sp1.
