Hi. Probably answered a question like this a zillion times, but since I've changed the compatibility mode to Windows 7 on my Windows 10 laptop, Movie Maker's been working fine with ALL of my projects until now! Please view the image below. I've muted the sound on most of my videos and added music underneath. It shows nothing but a blank screen on the preview screen nor does it play when I click play! It has only done this for the project in the image below. Help!
