Various Membership 2 Pro Issues

Hello, We are having various issue with Membership 2 Pro on our site. We have Paypal standard set up with the ipn and set to live but we are getting an error when trying to register a new account for our membership, we get: Registration is currently not allowed.

The Membership is active, as is paypal. Another issue we are having is that we are unable to test the registration page as it will not show. We had membermouse install previously but it has been deactivated.

We only have one membership level currently that is $5USD a month.

Also, when it shows the price of the membership, underneath it is showing a monthly price of $15, which is wrong and I don’t want that there. How can it be removed?
