Does Membership2 Still have subscription levels?

Does the new membership plugin still have subscription levels? I had quite a few pricing tables, etc, drawn up using URLs such as this:

http://aupairandtutors.co.za/register/?action=registeruser&subscription=6

But now these links don't seem to work correctly - members are registered but are not assigned a membership level. I tried using the membership ID as shown in the "Memberships" page of the plugin, but this didn't work either.

Your help would be appreciated.
