Problems using Membership plug in with BP corporate

Hi, I installed the latest version of BP corporate ( 1.3.4 ) with Wordpress 3.0.4

I've installed the membership plug in and i encounter some problems

I created as advised in the instructions of use of Membership a registration page with the shortcode [subscirptionform]

I entitled it (adhesion)

when i open the page i can't see the membership subscription form.

It looks like this theme is not compatible with that plug in.

How can i edit the code to have the subscription form visible ?
