I have WW too, have never perfected any items on it sadly. Even the most converted of all outfits the MFD giggles. But, trying this CrossDresser is perfect for someone like me, mainly because I am lazy/lack-of-time to read, too much on how-to's & fidget, twiddle and forever a novice.
So far the items I have converted, which was actually an old V2 outfit by BVH, in chain's and had jewels to V4, came out wonderful. I like the fact that I didn't have to load a figure into Poser then switch again to another model for conversation. Was just a simple load and click directly from the software thingy. As for the pricing, 'I think' if I understood it correctly, you don't need to pay both types of license just one. So $9.97 for V4. I'm happy at least, got a few extra outfits now for V4 weee..
