Hi - I’m afraid that I’m not aware of anyone on this forum actually using DIVA.
I see that their discussion forum is gone now but they seem to be saying that they will support DIVA until the end of 2020.
The Learn DIVA for Rhino
button on the following page has an address for eMail support - you could try contacting them that way…
