New Themes, Coursepress, Course shortcodes

Hello, I'm working to set up a test site before doing too much theming/etc.
I installed the Scribed new theme, and using Coursepress.
Shortcodes are not working as expected : http://www.adventureartretreats.com/courses/

They are installed on the page but the course is not showing.
This is on the page, but does not show up. I thought if you used the shortcodes you could control how these sign up buttons work. Please explain.
Thanks-
[course_join_button course_id="1"]
[course_join_button signup_text="Sign Up today for Course # 1!"]
