Redirect student to login page

When I link to a new unit in my Coursepress Pro course course and the user isn't logged in, they are redirected to this page: http://members.unbeatablemind.com/courses/kokoro-yoga-30-day-challenge This page has no link to any lessons or info. People are confused by this... how can i set users that arent logged in to be sent directly to my login page?
Thanks,
Rich
