Duplicating A Course is not working

I have been experiencing an issue with CoursePress Pro for weeks, and felt that I should bring it to your attention: Duplicating a course does not work. And, sometimes, creating a new page does not work. I get a server 500 error message page instead. When it does work it does not duplicate the course to the full extent. Only like 25% of the course is actually duplicated. With the page issue, a new page is not created. Instead, a new section is created within the same page.
