Registration form and mailing list

Hi,

I've got a site set-up using BuddyPress.

The problem I'm finding is that I have the Constant Contact API plug-in set-up - and its supposed to show a mailing list signup box when a new user registers.

I've tried creating a new user but nothing appears on the page.

I've got the BuddyPress setting... "Disable BuddyPress to WordPress profile syncing?: " set to NO.

Does anyone have any idea where I can start looking for a solution? I've submitted this to the wordpress, and plugin forum - but no response as yet.

Has anyone come accross this before? I'm at a loss to know where to start.

Thanks for any help anyone might have .
