Moved to ePO for better support.
How are you performing SQL backups? Do you know if you are using the simple or full recovery model? It might be easiest to restore the DB from whatever previous point or attach an old DB and point ePO to it with minimal data loss.
Are you DoD by the way? If so send me an email at brian.berger.ctr at mda.mil, I can better help you on there.
