Update: The 'porter' only knows basics of his tools, could offer no help.

I'm at a similar level with Blender.

I've tried using Autodesk's classic FBX toolkit to export that file as '2013' or '2012' versions. Files again crashed Poser...

FWIW, Open3Mod Viewer refused to open the original, claiming some sort of memory overflow into 'protected' areas. IIRC, a similar alert appeared in 3DOC after Windows 10 tightened its 'paper walls' between programs. Needed PNGs' alpha-channel handling error-trapping to 'non-fatal'...

Is any-one able to try importing this to recent Poser running in earlier version of Windows ??
