Storyline will not play all my slides.
I have a "cover page" slide (screen capture of a ppt slide) and an "end page" slide (recorded the same way). In between is a Articulate Replay screen capture mp4 video. When I preview, I get one problem: does not play end slide. It just shows as a black slide. When I tried to fix the trigger (which look normal btw), the video plays normally, I still get a black slide at the end, but the mp4 is skipped over (it shows maybe half a second and that's it). The whole video lasts about 3 seconds! Help!
