I have tried all 3 versions with the same result. When first I load the EC135 it runs for a short time and then the attached error comes up and the sim crashes. Once this has happened the first time it is impossible to load that version into the sim again as it crashes on startup every time after that. I have tried pushing the "Retry" button on the error message and the sim still crashes. I have also tried reinstalling the same EC135 version again and the sim still crashes on startup. Note that I have multiple helicopters and fixed wing aircraft and the EC135 is the only one that I have ever had any errors or crashes with. I note that at least one other member on the forum has also had this error. I look forward to finding a solution. Regards Rob (Tassierob)

Not a bug, but a misconfigured command. If you have a similar problem, delete and reconfigure the joystick's preferences.
