Absolutely wonderful you found some time to convert the plugin! Very very much appreciated because, as many above have already said, your plugin is really a game changer.
I ran into an error at the start of a LM calculation that stops your plugin to kickoff - see pic. Any suggestion what to do?
edit: spelling & using 4.20.1

I am getting the same error, but thank you for at least building this version. Any suggested solutions?
