Problem With Events Plugin Please HELP ASAP

When I try to make links active in a events listing the error comes up. It will let the link be regular text.

the error:

Fatal error: Call to undefined function ke_getPluginLocation() in /homepages/10/d333854264/htdocs/wordpress-3.0/wordpress/wp-content/plugins/kino-event-calendar-plugin/tinymce/jscripts/tiny_mce/plugins/imagemanager/config.php on line 27

Any help would be great!
