I can't click to next page when install SEF advance

I need support with SEF advance. When click next on the products display in virturemart, it says  "The page isn't redirecting properly. Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies."

I don't think it has anything to do with cookies. I am using joomla 1.5.10 and virtue mart 1.1.2.

Please see it for yourself by clicking on the link, scroll down to the bottom and click next to see the next product display page.

Turn off Redirect non-SEF URLs in SEF Advance configurations. And other redirects if that doesn't help.
