CoursePress Pro is not working

I started with a question about the answer field and why it was not showing up on my preview of my coursepress pro course but I'm unable to reply to that initial question for some reason. I love the idea of this plugin and it seems to work very well on the backend; but, when I tried to add myself as a student and see what it would look like, I can't even get to the course; when I click on it, it only shows me a page with the title and description, nothing is clickable and no units are visible.

I have updated the plugin and done everything I can to try and figure out why it's not working; the answer fields are still not visible when I preview the course from the backend; but, making the course seems pointless if the students can't see the information or the questions.
