Issues opening Storyboard Pro's .sboard files on different computers

Hello, I’m having an issue where when I open my storyboard file from one computer to another computer that the drawings don’t show up. I could see the drawings down in the thumbnails but not on the canvas. Please help if there’s anyway to fix this.

I have also same kind of issue but if opening files on different computer you must first deactivate the license and return it to Toon Boom Animation.
