Magic Submitter Database Help!

My computer died a sad and lonely death this weekend and I had to get a new one. I'm trying to get my database copied over from Magic Submitter. Not the last backup (because I had of course just made a bunch of accounts and didn't back it up.) My backup doesn't include the new accounts. I've looked and looked and can't figure out where the actual database file is. Does anyone know? Can anyone help? Thanks.
