Subscribers unable to select "Contact" page

I am having an issue with the membership plugin. Subscribers are being redirected to the "content is protected" page when the select the Contact Us page. I am using Contact Form 7 plugin and have added the shortcode, however, when I select the box for that shortcode, save and test, I get the same error. When I go back to the option to select the shortcode, the box is no longer selected.

I am re-posting because I have not received a response in the original posting.

Please help! I need to launch the site!
