Rhino can't find valid Maxwell license

Hi, after installing all the three applications from scratch: Rhino 6, Maxwell Studio and Maxwell Render for Rhino (including Maxwell’s RLM license manager pointing at localhost as these licenses are called from different computers on the LAN) both Maxwell apps work fine. The only thing that does not work is the Maxwell Plug-In in Rhino pretending not to be able to find a valid Maxwell license. What can I do? Best wishes!

I’d contact Next Limit - I had a licensing issue a couple of Maxwell generations back and they sorted it quickly.
