I am using Sketchup Free for a home design (not commercial use). I have been working on something for 3 days. Today I imported what I assume was a large design from the Warehouse (a tennis court) and the whole system froze. I got a pop up saying that Sketchup Crashed which I had to fill in. Since then it said ‘saving’ in the top of the screen and now it has gone black. I saved on trimble every 5 minutes. When I go on to trimble I can see my design there but when I open it it takes me right back to the black screen. I don’t know if I must close the black screen and re-open? I need help retrieving my design so I can carry on working on it. Please help!
