Everything working but the admincp

My problem is like this: I installed iProArcade on my vbulletin 3.64 and everything works but the admincp side. No mather which page in the arcade section I try to chose, it says page cannot be found.

It works correctly though @ www.sportti.com/foorumi/arcade.php

Any Clue?
