Filter Forge 6 Pro - fails to work as a plugin in Affinity Photo.

Hi gang, I see there has been some discussion on the internet about this over the last yewar or so. My understanding is that FF6 Pro should run as a plugin in Affinity Photo. FF6 shows up in the filters menu as I would expect but when I run the plugin I get the attached message.

I am running latest build of Affinty Photo, and version 6.010 of FF6Pro which I understand is the latest. My Affinity prefs are set up as look for the plugin in the folder "c:\program files\filter forge 6" and the tick box allow unknown plugins to be used.


What idiot thing am I doing wrong????

Cheers
Steve
