Can't get registration form to display

Not sure what I'm doing wrong. Been over this a bunch of times...

Created Access Levels, activated. Created Subscription Plans, activated. Created a sign-up page. Added the [subscriptionform] shortcode.

The page displays the option to select the Paid Access plan, but there is no registration form--no "Step 1" just a Step 2.

There are NO other plugins running on this site. I also thought it might be my theme (formatting is a bit messed up) so I switched to the default 2011 Theme and same thing--no form. Running WP 3.3.1

Here's the page: http://wpvid-marketing.knowapp.com/sign-up/
