Fatal error: Call to a member function getUserState() on a non-object in /home/ilwu/public_html/modules/mod_eventlistcal15q/mod_eventlistcal15q.php on line 119

This only comes up when I have another module... ninja accordion... I have contacted them as well o see if I can get the two mods to work on the same page but I figured since it comes up with a eventslistcal error you guys might be able to help

you can see it at ilwu13.com/index.php?option=com_content&...p;id=1&Itemid=65
Thanks
