Membership Plugin is not available to me


I've been having a bit of trouble with the membership plugin and it's communication feature.

I just noticed that my list of plugins on my dashboard only lists "Appointments +" which I had traded for the "Membership" plugin shortly after the new year.

Could that be causing the issues with the email sending?

I was wondering if you might be able to reset my permissions to "Membership" only so I can test this out?
