Membership with buddy press and Pie Register

Hi,

I'm trying to use Pie Register in a site with Membership and BuddyPress.

Now my Pie Register form works fine but I can't get it to work with Membership. When I click on the button in order to choose the subscription level I got always the Buddypress registration form and not my Pie Register form.

Could you pleas help me?

Bye

Carlo
