Marketpress Products not showing - all other pages working correctly?

I've got marketpress installed on several sites, and got the latest updates on it. One is a m/s other is regular wordpress install. In both cases, there are products entered, but it won't show them on the products page...

provector.us
cocosonthebeach.com

The normal store, shopping cart, and check your order pages are working fine, but products doesn't..

I thought it might be a plugin on the cocos site, but when I updated the provector today it's doing the same thing.. I have it on another site that I havne't updated and it seems to be working fine ?

Thanks
