Hi, my first post and newbie…
i get an error message when trying to open a karamba example file that uses octopus, the error message i get relates to HelixToolkit.Wpf.dll (see attached screenshots).

I have reinstalled this DLL as suggested here from a post in 2016
I am using Rhino 6.25.20114.5271; GH build 1.0.00027 and Octopus 0.4
The karamba file i am trying to use is here
Any ideas?
Thanks
