Membership Plugin not assigning proper levels automatically

Hey guys.

I have some subscription plans set up on my site and for whatever reason, when some one signs up for that level it does not automatically assign them to the proper access level. This is probably just an educational piece for me where I am not doing the right thing but any and all help would be greatly appreciated.

Oh and I granted access to my wp-admin via the support feature in the WPMU Dev plugin.

Thanks again guys!
