Hi
Is this a new installation or one that was upgraded?
If it is an upgrade IIRC we are backing up the database prior to the upgrade so maybe it is possible to search for this backup and getting an older version of your DB.

If the DB is deleted and you have no backups you will probably have to reinstall.
I recommend to backup your DB on a daily basis using our backup.sh script , you can use a simple cron job for that.
