Accessing Membership Plugin Settings

Hi, for some reason my membership settings are not displaying on the menu bar in the admin panel. I went into the WPMU DEV dashboard and hit the configure button for the plugin but it gave me this message:

You do not have sufficient permissions to access this page.

I am sure this has occurred because a while ago my site was hacked. Through FTP I had to recreate my admin account because it was deleted. How can I gain access back to the Membership plugin settings? Thank you very much!
