WP-Cumulus widget not working in my sidebars

Hello,

I have been trying to use the WP-Cumulus plugin with WP 2.9.2 and Atahualpa 3.5.1 but whenever I add the widget to either my left or right sidebars it only shows a static list of categories and a note at the botton saying that I need to update my browser's flash player to v9 or higher. I have the most up-to-date versions of flash player in both FF 3.6.3 and IE8, and have been able to run it properly using other themes. This is the site where I want it up and running: http://blog.lldmvalledeluces.org/

Any suggestion you can provide is much appreciated.
