second page of register not showing a button to select for subscription type

Hi,
I just installed membership and have followed the instructions, I think! I have activated global tables and plan to use it to restrict access based on url groups (to certain subdirectories across the network, but not pages, categories, etc.)

It looked good until i got to the second page of the registration process where it asks to select a subscription - there is no button and no way to navigate from that page.

The subscription is free, and i will just have 2 groups - unregistered users (stranger level) and registered users (can see certain subsites that unregistered users cannot.

Help!

Thanks.
