DXO NIK in Affinity Photo

I have just installed the original DXO NIK and then the Upgraded DXO NIK to Affinity Photo, and both lock up in AP but Google NIK works fine. Any idea why? After paying for DXO NIK I expected it to work?

Yes, this is a known and aknowledged problem with using DxO NIK with AFP on Mac.
