When I view the mov file for my animation, it's a black screen

Hi Everyone.

I was recently working on an animation with stick figures. (They were Black Stick Figures) I exported it with no background, then watched the mov file. It was a black screen. I was confused at first, but then I remembered toon boom automatically makes an animation with no background have a black background. I gave the animation a white background, exported it again… and It’s still a black screen. I’m new to toon boom, so if i’m doing something wrong, please tell me what it is. Any help is greatly appreciated.
