I just purchased PI 3.0.2 and I'm having a problem importing anything into it. I am able to choose a file (in this case a JPEG file ) and it goes through the "image is not the same size...make stage same size as image?... I choose okay and then a window comes up:Background Image. with dropdowns for: start at project frame(1); hold last frame(0)(this is checked); separate fields(set to off)and remove. I click OK and the screen remains black. Any suggestions?
