Error starting simulation in mission planner

ArduPlane Plane Simulation

Hi.

Following this guide https://ardupilot.org/dev/docs/sitl-with-realflight.html

After selecting flightaxis, when I click on one of the aircraft type icons it says ‘downloading sitl software’ then I get this error:

sitl-error
sitl-error651×516 209 KB

Any ideas?

Ok, installing the MP beta fixed that…

Now sitl connects to realflight.

Next issue - when I try and load a param file in MP, I get this error:

Does anyone else see this error starting loading SITL params in Mission Planner?
