code extinguisher (codex) login system

[eluser]ocergyNohtna[/eluser]
i tried removing codexlogin from the autoload but i get an error:

Call to a member function setPreDefinedAccessLevels() on a non-object in /site/htdocs/cps/codex/application/hooks/loginhook.php on line 19

what else should i need to do so it's not loaded??
