Membership Plugin Allowing Access Without Paying

I’m using the membership plugin on this site: It works well except for one thing.

1) Users can cancel out of the process and still can go back to the site and access the membership content: It is giving them access when they create their accounts and not after payment.

I’m guessing this is a setting on my end that I have configured wrong. Can y’all point me in the right direction to get this fixed?

2) Along those lines, is there a way to email those members who are not active paying members (after I go in and manually deactivate them till they pay).

Thanks for your help!
