First you might try double checking to make sure that you are importing the correct course and semester. We import all of the online courses for our college. Occasionally we choose a course either from the same semester we are in, or a future semester, neither of which has content yet. So the import appears to be working correctly, but there was nothing in the initial course to import.
The other possibility is with the settings. You are given the option to import all content or choose specific content. If you select the choose specific content you will get a second window which will require you to select each item you want to import, and then import the content.
If neither of those options are helpful, you might try exporting the course that you want to import as a course file, and then importing the course file, rather than importing from the course.
If none of those options work you'll have to contact support. You should have a ?/help button in your course. They can look at your specific situation. Good luck!
