Sorry, I just saw this... I'll have to go look around to see what the crash bug might be, but in the meantime, here's a few notes on the settings you're using...

Scale Factor - I use 1000 on import and 1000 on export for Poser figures.  I typically load some Poser figure in (at 1000 scale factor) to use as a reference inside C4D, then make my models relative to that figure/scale.  Then when you export your model, leave the Scale Factor set to 1000.

Reverse Faces - You should have this enabled when exporting for Poser (or for C4D, for that matter).

Mesh Names/As Groups - If you set up selection tags for your groups and then added a Riptide 'Group Tag' to track them, you should not use the 'Mesh Names' option.  It will just add confusion to the naming.  The group names will be the same as you used for your Selection Tags.... which is what the 'Group Tag Names' option does (if you have a Group Tag set up on the mesh(es), it looks in there to get the names).

Let me see if I can figure out the crash and get back to you.
