CoursePress Pro course links broken and students missing

My installation of the CoursePress Pro plugin disappeared, which I understand was(is) a known issue. I re-installed it and my courses all returned, but now when I'm in the dashboard and click to view a class, the link is broken. "Oops that page cannot be found", but it previously worked.

Here is the link to my site: http://wordpress.barrow.k12.ga.us/bcssonlinepl/courses-dashboard

Also, I had someone who was testing the course for me before the plugin disappeared. On her dashboard she is still enrolled, but on my end I have no record of her as a student or anything she has completed.

Any help is appreciated to get the links restored and the students, too.

Thank you,
Caroline
