Content is "disappearing"
I am working in Storyline 360. When I open up a project, I can see my content in the story view; when I open a slide the thumbnail view on the left is blank, and the slide view in the center is blank, but the timeline still shows all of the items that should be showing up. I have opened two different projects and the same thing is happening. I just upgraded to Windows 10 but I see that SL360 is compatible.
Any thoughts on what is happening and how to fix?
