A while down the road now, but I learned what the problem was. When you import a scene with a cloth object from Poser, you must allow the "animation" option in the import option box when it pops up. When Carrara 5 Pro imports the file, it opens it to the first scene of the "animation" i.e. before the "cloth" was draped. You have to advance the animation bar to the far right to the last screen of the "ani" and you will find your scene as it was at the time of export.
Remember...Think of a Cloth import as an animation. Make sure you make it scroll all the way to the end of the "ani".
