My preview screen is black. I've got the video in my timeline, a soundtrack added. I can play it and hear everything. This is not just on my projects, even the sample project. I saw a tip that said to go to file>settings> and make some changes, but I can't find "file" to try it. It has worked before, but I have no idea why it's not now. I have a new laptop by Dell that meets all specs to run this program and more. It's what I bought it for, so it shouldn't be a compatibility issue. Can someone please help me? (As you may know, I'm new to this program) I'm using Movie Studio 16 Suite.
