You'll need the latest/greatest GP package installed... you can get that here (Monk uploaded it): https://zonegfx.com/golden-palace-for-genesis-8-female-6-2019-updated-version/
Install that, then I believe you'll be good to go.
As for the CZ product, I tried using the thing, but it seems a bit too limited in range-of-motion to me. Probably takes a bit of work to get the hang of it though (Note: this is likely my fault. I was expecting controls similar to the old EasyPose rigging, like the old Poser tentacle sets have. I loved the ease and speed with which that could be set up.)
