I'm still getting the same black screen. I updated all of my drivers and tried F9 changing substance engines and nothing helped. All of the other builders show the same totally black screen- wood, fabric, etc. I don't know if this helps, but if I click my cursor around where I think the menus are in the upper left, I can get them to show up. It's always worked fine for me and I'm still on the same computer. For the life of me, I can't think of anything else to try.
