Render Doesn't Work - Following Training Course

Afternoon All,

I’ve just downloaded the Synfig Studio software, and just purchased the video training course. I’m on the third lesson where it is showing how to render and export the animation of the boy moving between home, school, and the shops. Everything plays just fine in the software, but when i follow the directions to export to a .avi file the result is just a black 5 second video. Any suggestions?

Current setup:
windows 10
Synfig Studio 1.2.0



please refer to my answer here
