Can you Help

I have Paid Memberships Pro, love it. I installed the bbpress add on and set up a couple of forums. The problem is only the admin can see the posts. As a user who should have access I can see the list of forum topics in the proper forum but when I click the topic I only see a place to reply. I read on a forum somewhere that I should deactivate Paid Memberships Pro and then remove and reinstall it but I have member accounts on the network who have their own sites going and I don’t want to mess anyone else up. Have any suggestions?
