This has just started happening to me. I have Poser Pro 11 and all the latest updates/SR's installed. The scene in question is only the EZdome, one figure with EZSkin applied, and 3 dynamic cloth props with associated cloth sims. When I attempt to load it to keep working on the scene, Poser crashes.

How do I fix this?

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
