Dupal Wunderkind installation

Hi
My website has gone wonky and so Im trying to reinstall the Wunderkind theme. I follow the instructions, but when all said and done I get this message

Fatal error : Call to undefined function _nikadevs_cms_get_active_layout() in /home/www/thetapedispenser.co.uk/sites/all/themes/wunderkind/template.php on line 29
