Plugin from hell

This is the plugin from hell. I installed it, it removed my plugins section (I get “access denied” for mysite\wp-admin\plugins.php)now I can’t remove the thing not add/modify any other plugins. Also did a lot of other weird things. No support from the authors. Site is still working, but to get rid of this piece of crap I’m going to have to basically redo the whole site. Stay away from this thing, I’m sure there are a lot of other user manager plugins available that will not cause you any grief. I give this thing -1stars (tats negative one)
