Not working

Hello everyone

I recently installed this add-on and can’t seem to get it to work with my theme. It works great with Twenty 11 but not with my theme of choice, Desktop Chaos (http://www.desktopchaos.com/). I’ve made sure to add the header and footer hooks to both my header and footer.php but it’s not helping. I’ve reached out to the theme author for extra support but any and all assistance that anyone here may be able to provide would be greatly appreciated.
