yamaden on "[Plugin: Another Wordpress Classifieds Plugin] Category Page Not Found"

Hi,

I have been trying to set up classified page in my site by using your plugin here. For some reasons, when I click any categories, pages are not found. Please see the following site and click test category.

http://www.thestardust.us/classified/

Could you tell me how to fix this?

Thanks!
