Can you drop and re-create your database? I know it's a new installation, but it seems like the DB was partially initialized once and then reused with this installation later on.
This would mean to drop the db, create a new one with the same name and account to connect to it, re-run the configure script once, then start services again. Please ensure there is only one vCloud Director being used with the installation initially, as we can always add cells later via a different set of steps.
The errors are about decrypting files, which means that some of the ID keys generated don't seem to match the local OS files.
