Cant save Usergroup settings after upgrade to vB3.7.0 RC2

[Rukas]

Ive upgraded and in the process I got rid of some of the plug ins I had installed, one of them was the chat. Unfortunately even though it has been deleted the settings table is there at the bottom of the usergroup, even though it is blank, and when I save I get the following database error:


Database error in vBulletin 3.7.0 Release Candidate 2:

This is caused by a custom addon for additional permissions. You need to contact the author of that addon or delete its XML file from includes/XML.

or delete its XML file from includes/XML.

Perfect thats all I wanted to know is how to get rid of it.
