SQL Error after removing an addon

[gwon]

I installed an addin using the plugin system on vb. Didn't like it and removed it. Ever since, whenever I try to make most changes in the admin panel (noticed it first when trying to edit usergroups) I get the following sql error

Database error in vBulletin 3.7.1:

This bit: mgc_cb_evo_permissions, leads me to the plugin, I seem to remember the name was something like that. So I'm assuming that it's calling parts of the database that aren't there...or something along those lines.

Does anyone have any idea how I can get it to stop chucking through these requests and causing the errors?

Any help much appreciated.
