I have not seen Adobe Classroom in a Book Premiere Elements, but most of that series now uses MOV files for the exercises.
Do you have Apple's QuickTime Player installed, and if so, which version.
What happens if you transfer these .mov sample files to the computer hard drive (desktop) and then use Premiere Elements 11 Add Media/Files and Folders to import the videos into a new Premiere Elements 11 project? Do you get the same error message that you get when you are trying to get these videos directly into the Elements Organizer?
If you go Premiere Elements first, what you import into Premiere Elements will be automatically copied to the Elements Organizer.
This would be a good troubleshooting step for now. We can decide later how this fits or does not fit into your workflow next.
But, as where Hunt's question is leading, installation of QuickTime (latest version) is a program requirement.
Looking forward to your follow up.
Thanks for your help. Problem solved. I installed Quick time 7.7.4 and
re-loaded the lesson videos into the Organizer.
