Odd.  Might be some problem in the Poser files that Carrara is stumbling on.  I had a corrupted texture map recently that Poser dealt with by not loading it, but Carrara crashed completely on.

For full dynamic clothes, set up the animation in Poser, do the dynamics simulation, save the file.  Then open that file in Carrara, with "keep link to Poser file" selected.  That, at least in my experience, is how you get the entire run of the dynamics into a Carrara scene.  Even if you don't chose to render an animation, I like being able to pick the best frame of the simulation from within Carrara.
