I have the same issue. Purchased the aircraft yesterday (Sep 4) through iniManager, iniManager is on latest version. Had an uneventful first flight on MSFS 2020 and now the next day it just won't work. All lights of the aircraft are on, I can push buttons and turn knobs, but the aircraft won't react. I do not fully understand the troubleshooting steps with deleting the iniManager folder in Local and Roaming folders. As when I delete them and try to relaunch the iniManager, it just says that Windows cannot launch the app as it cannot find it anymore. Am I doing something wrong? It is so weird, as I had no issues yesterday and now all of a sudden nothing works.
