Great ideas - thank you. I'm going to check the Table Prefix now.

I am trying to figure out how to check this via phpmyadmin, pointers?
It's not a phpmyadmin setting, its a config setting. To figure out what the table prefix is look at the vbulletin tables names and see what is in front of user, or usergroup, or forum, etc, if there's something in front of the table names above you need to add it into your config.php file.
