Issue with admin.comprofiler.controller.php

Hi,
after installation of the com_comprofiler, i always get this errormessage

Fatal error: Call to a member function authoriseAction() on a non-object in <span>/</span>var<span>/</span>www/vhosts/blablabla/httpdocs/administrator/components/com_comprofiler/admin.comprofiler.controller.php on line 74

Installation was succesfull. CB is not usable.

Is there a solution for it?
