Long story short, it sounds like moving aside the LayOut .plo files fixed the crashing problem. Funny thing is that the permissions looked ok, but there must have been something else going on.

@ntxdave said: @dave r said: Did you explicitly set permissions for the SketchUp Plugins folder to Full Control for your login? It doesn't sound like it. Yes, and I went to my old computer to check that they were set the same. I am not seeing the difference. I just went back and checked again and my login was not set. So I set it (again), now all seems to be working fine. Thanks for replying. I do not know how the permission did not get set before.

There shouldn't be any "hidden styles" in your model. You should be able to see any styles in the In Model styles library. But just to be sure, open some of the components individually and take a look. If you are getting components from other sources, it is best to check them out carefully before using them. This would be especially true with components from the 3D Warehouse.

Have you already created a 3D Warehouse account at all?
