I have purchased Movie Studio 18 Suite two days ago and I am having a lot of problems.
The view that I get is very different from the tutorial videos. I can only see the top screen but not the timeline at the same time. True, I can change the top screen to different display modes, but it doesn't help at all. When I play on a clip preview, I can hear it but not see it. When I maximize the program (Alt + Enter), I can only see half the screen (the right half) and I still cannot see the preview.
Moreover, I cannot see the program monitor and timeline below as appears in your tutorial videos and on page 32 of the manual under "Edit interface"; I can only see the program monitor.
