This is really close to breaking me, and YES I've been through the manual on importing props. Now when I try to import a set as a prop, all that comes up is one bright pixel. Nothing else. I've tried three times, and that's all I get. I'm exporting the whole product file, so it can't be that. 
I was able to import ONE scene only, and that one causes CC to crash every time I try to render. 

I feel like I'm going out of my MIND here! I know you people have helped me, obviously enough to get sick of me, but PLEASE help me one more time?
