CoursePress has no course to update from 1 to 2 but still shows the notice

My site is asking to update my courses as I updated from CoursePress Pro 1 to 2. Well, one of the many plugins in my site conflicted and I couldn’t update the courses. After running a plugin/theme conflict test, I was able to update the course. But after a while, it asked me to update the courses again but when I entered the update screen, it says there are 0 courses to update and clicking on the ‘Begin Update’ button does nothing.
