In Response To: Chunks Down Help (Knox, Ernest)

Have you tried to restore the database from your last archive? If you have created all the appropriate links on your drive for the dbspace that was lost, I believe that the only option for recovering, with your older verion, is to restore. That should fix the database and mark your dbspace online.
