After installing the 11.21 revision update, the program stops after I click "Start Flight" with the following message:
Be Advised
Couldn't load the sound bank!
Master Bank.bank
(veh_planes_read.cpp:2491)
I get a button to click ("Undestood"), whereupon the program stops. I reviewed a previously submitted question of a similar issue where the Answer recommended moving the "Sounds" folder from where it is supposed to be, and then running the X-Plane 11 installer.app. I tried that with no success. Any help would be appreciated.
