Hey, i followed the instruction on this topic right here →
[I cannot load any different airport and plane - always the same airport and same aircraft - non ascii windows 10 account name - #75 by paranoidharry]
but as you can see inside the topic the path is : C:\Users\your name\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\MISSIONS\Custom\CustomFlight and they guys said you have to delete CUSTOMFLIGHT.FLT. I have deleted CustomFlight.FLT wich is the wrong file and now all progress from trainings is lost !
Any way to get it back ?
