Multisite Permalink Structure with Marketpress not linking

Hey, it's Roxi
I have a multisite with marketpress & prosite. On the main site the permalinks that should take you to the member store sites come back as " page not found" in anything but the Default Permalink, BUT in the Default Permalink, marketpress, buddypress and other related plugins don't work. http://senergyplace.com/senergy-mall/
What should I do?

Thanks, Roxi
