The latest version released in Andrew's thread is the a working version. Island Paradise didn't require any special update since mermaids use the same skeleton as regular sims. If your pose player is not working then you either didn't download both files, didn't unzip pose player or have duplicate pose player files. It is reported working by hundreds of players.
Please don't DM me here or elsewhere asking for assistance with Ninjaripper or CC. I don't work in Ninjaripper anymore. Please post your questions in Creator Help thread so everyone can chime in and help solving the problem
