Using Coursepress Pro with the Divi Theme


I've been using a child theme provided by Nithin from the following post:

The latest Coursepress pro update is causing a lot of errors and they all seem to be related to the course class being removed. (PHP Fatal error: Class 'Course' not found).

What do I need to do to get this resolved or can I revert back to a previous version of Coursepress? The update reconfigured the database so I'm not even sure that I can revert back. Please let me know.
