Classifieds Plugin Causing 404

I have a buddypress/bbpress website that also has multiple additional custom post types. After adding each new custom post type I would update permalink settings to correct the 404 not found occuring with that post type. However this would not work unless I deactivated buddypress first then updated permalinks then reactivated buddypress. I am almost doen with the website and one page that displays the "classifieds" custom post type is still 404ing. The "My Classified" page works along with individual classifieds. All other pages work. If I set wordpress permalinks to default then the page works.

Has any one lese heard of .htaccess problems with only one page in wordpress?
