Hello,
Sorry to hear you are having trouble.
I think it has something to do with Microsoft Flight Simulator 2020
Ok, I need to ask something, if we remove 'Sim' (Microsoft Flight Simulator 2020) from the equation, and it's after a reboot of each PC, and Sim is not started on either, do you have this problem - is there and issues with using Multiplicity?
