Need help removing a template mod

[Fastbird]

I installed an addon and it created some permissions in the usergroup manager. I uninstalled it and it did not uninstall the permissions. Now I get a DB error because it's corrupt. I tried to reinstall and it did nothing.

Here's the error:


MySQL Error : Unknown column 'uscpermissions' in 'field list'
