Membership plugin: no access to BuddyPress pages - any way to debug rules?

Hi, everything used to work, then something happened, and now Membership redirects BuddyPress Activity, Members, Groups and Forums (and Achievements) to no access page no matter what level I'm in. Tried to remove *ALL* rules from the levels, still can't access ANY of the BuddyPress features. Subscriptions are active and public, members are active. As soon as I disable Membership, I can access BuddyPress again, so it's definitely the Membership.

Where's the code that drives that logic? Any way to debug it? My site is on localhost at the moment. Any quick and dirty advice, like cleaning SQL tables?
