Error "Class 'KunenaRoute' not found"

Hey!

If i activate the Plugin "Forum integration" i get the debug-message: "Class 'KunenaRoute' not found in ... /users/USER/www/components/com_comprofiler/plugin/user/plug_cbsimpleboardtab/view/cb.simpleboardtab.tab.php on line 93".

I´m using Kunena 1.8 on Joomla 1.5.26.

Also i get the following Feedback as this point who is placed the login-Form, if i logged in:
