After the update to 11.21r2, when I try to start a flight, it start to load the flight as usual then it gives an error about not being able to use the RESOURCE/DEFAULT SCENERY/AIRPORT SCENERY.
I tried to delete it and then to re-install it using the installer, it re-created the folder, and again it still gived the same error.
I tried to just delete it, and then it started to give error about one content of the CUSTOM SCENERY after the other.
Right now the simulator is completely useless as it can not be use to start any flights
