That's odd.  I use Carrara for all the posing so I just pull the base characters into Carrara from the content folder's runtime folder then drag and drop morphs, clothes etc. from the content tab.  Remember some morphs require you to have some base morphs like the morphs++ for V4.2.  Also, in Carrara, you need to set the correct parent mesh to the clothes and hair once you pull in any clothes, hairs or props.  Some also require you to use the magnet fits for some figures.  I find it much easier to do the posing in Carrara.
