Membersip plugin won't allow blog creation

I have a network setup with buddypress and the membership plugin activated.
I've set up all of the proper levels and subscriptions. All good.
But when I log into a users account (wp-admin.php), none of the admin menu items that I have allowed for that user level show up in the admin area. I want to allow blog creation for certain user levels but on the 'blog creator' user level (or any level) it only shoes the dashboard with 'My sites' underneath and won't let me create a blog.
Any idea why this is?
