MarketPress/Framemarket: urls don't go to correct posts

Ok here’s a weird one:

We created a post and the url for the post (as shown in the permalink section just under the post title in the new post screen)

The displayed URL is http://www.nbw.ca/a-new-test/

But when you go to that URL you wind up at a product category top page. ( ??!!)

Changed the permalinks, changed the permissions on the .htaccess file to 777 and changed the permalinks (put it back to 664 of course), made sure the rewrite code was in the .htaccess file, updated all the plugins (except framemarket as we had to kinda hack it quite a bit).

I’ve been WP’ing since 1.5 and have NEVER come across this, Anyone have any idea what the what is going on?

thanks
