Fatal error with jomsocial

Will someone please help me with this.

When using the jomsocial template I recieve the following error when I login or select the profile tab and it only happens after I create a group:

Fatal error: Call to undefined method stdClass::getLink() in /home/xxxxxxx/public_html/components/com_community/templates/gk_style/profile.groups.php on line 24.

I really need to get this fixed and some help would be appreciated.
