I am having trouble importing files from a vendor that were created in Storyline. If I unzip the folder on my computer, I am able to view the content perfectly, but when I import the .zip file into a Canvas course and then add the .html file to a page or an assignment, I can see the shell with the title of the file and the navigation buttons, but just a black screen where the content should be. When I put my cursor over the screen, it spins as if loading but nothing ever happens. This is happening for about 75% of the files that I have tried to add to my courses - some have worked fine but many have brought up the blank screen. I have attached a screen shot of what I am seeing. Any help is appreciated!
