Membership update: content unprotected and gateways inactive

I just updated my Membership (premium) plugin to 3.0.2 on a WP 3.4.1 site and now:

– all my content is unprotected

– users are being redirected to a different downloads folder

– the payment gateways are inactive

Is this “expected behavior” when updating? Can you point me to some instructions on how to remedy this, and prevent it going forward?
