ArchiCAD Grasshopper Live Connection 2.0

So is there a combination of ArchiCAD / Rhino / Grasshopper that works with the ArchiCAD Grasshopper Live Connection 2.0?

I have ArchiCAD 21, Rhino 5.4 & Live Connection 2.0. Even though I can establish a connection via ArchiCAD, Grasshopper does not seem able to initiate a request for curve data.

Did you ever figure this out?
The message was not categorized so it fell through the cracks.

Moved to Grasshopper category and added ArchiCAD tag.

Hi, it would be nice to see some files or something to work with. I have managed to get it to work on several instances, it is awkward.
