I haven't used the app, so I don't know exactly what your problem is, but I know the game quite well. I would recommend verifying that the images with the same name, also have the same relative path from the "portraits" and "bodies" folders. For example:
...\portraits\Human\Blond\TitsM\SkinL\AssM\girl(1).png
...\bodies\Human\Blond\TitsM\SkinL\AssM\girl(1).png
