Restore MS Exchange 2003 using Data Protector Express

[GerardeArchimedes]

I originally posted this query in March this year but had no replies.
I am trying to recover an Exchange 2003 mailstore to the Recovery Storage Group. Apparently, by default, this is the default location for restores if a Recovery Group is created. At the end of the restore I get;
Error 3201: Stream Sync error, expected stream header for the First Storage Group.
If anyone has successfully restored an Exchange Mailbox store using this software please advise.
