HI

I have an error occuring whenever i click on a question / answer from within the admin area, meaning i cant edit / publish /unpublish any questions / answers

The error i am receiving is as follows -

Fatal error: Class 'CategoryTree' not found in /home/****/public_html/****.com/administrator/components/com_communityanswers/models/questions.php on line 161

Any help will be greatly appreciated :)
