For some reason after the beta patch I can't start the engine on any of the planes anymore. I do everything according to those instructions, but as soon as I hit "I" button I got a message engine: stopping

, before the beta I was able to start the engine without a problem.
I then tried to turn engine off in air. The engine turns off, but the message I got is engine: starting instead of engine: stopping
Any ideas? I Haven't changed any buttons.
I can't continue my campaign with CEM enabled anymore
