I'm using Poser Pro 2014 Game Dev, and I occasionally have a similar issue. I will start Poser, click on the File menu, try to load a scene I have saved, and Poser will crash. It doesn't happen very often, just every once in a while. Mostly, for me, it happens when I try to load a scene too quickly after starting Poser. I have a fairly large library of content at this time, so it is usually better to give Poser a few minutes to finish starting up and loading its libraries before I try to open a saved scene.

This is mostly a hard drive issue. My libraries are stored on a single drive that isn't particularly fast. It just takes longer to finish loading them. So if I'm patient, then it's not an issue.

You might be experiencing something similar.
