Membership not displaying in Dashboard

I've just installed the Memebership 3 RC1 plug in. It appears to work fine as I can browse to the differnt config options via url - but it doesn't show up in my dashboard. It's a pain typing in /wp-admin/admin.php?page=membership and /wp-admin/admin.php?page=membershipoptions. What could be keeping it from displaying in the Admin Dashboard?

Thanks
