Can't seem to figure it out.

Well me and some friends are trying to start up the iFlyFF source and end up getting an error everytime we try to back up the database. It says something like:

The media family on device 'C:\Program Files (86x)\Microsoft SQL Server\MSSQL.1\Backup\CHARACTER_01_DBF.bak' is incorrectly formed. SQL Server cannot process this media family. RESTORE HEADERONLY is terminating abnormally.

We don't know what to do and when we try to create a character with the Chatacter DBF we have now in-game it always says 'Name already exists'. Even if you re-log your character doesn't show.

Any answer I would greatly appreciate. We're stuck.
