I'm trying to download some material from a couple of different courses in Commons, and all I get is a tab that's labeled "cartridge-manager-iad............." The download never happens. I really don't want to import the whole course into any of my Canvas courses...I just want to see the pptx files to see if they'd work for my course. I checked the Commons guides for help, but can't find anything relevant. Am I doing something wrong???? (And yes, I'm an instructor!)
