Error in NewsGK4 Module in Joomla 2.5

Hi,
I'm getting the below error when I try & load a k2 article into the featured 'latest features' box in header1 position. Using Joomla 2.5.

Fatal error: Class 'K2HelperRoute' not found in C:\wamp\www\joomla25-BPgk_sporter\modules\mod_image_show_gk4\styles\gk_sporter1\model.php on line 121

It works ok when i choose a normal article rather than k2 article

Any help appreciated

thanks
gavin
