CSS added to admin.php

I’m not sure what has happened or if I’m responsible but I have no idea how to fix it (I’ve never seen this happen before)

THe plugins/wp-filebase/wp-filebase.css file is being loaded into wp-admin and the format and layout of my admin pages is all screwed up!

How did I include this file and how do I remove it?

thanks
