Wanted to board passengers and got couatl error which stated I needed to install latest Addon Manager. I exited FSX, installed latest Addon Manager, restarted PC and ran FSX. Got error regarding FSUIPC. I immediately suspected problem with Addon Manager so I uninstalled. I kept the Couatl engine and kept all my Addons. Now I can't get FSX to start without a stackhash error!
Thanks for any help to get me up and running again!
