I can use the keyboard with no problems but every time I open FL it gives this error and it's annoying. The keyboard is not in use with any other program, removing its cable and putting it back didn't work. If I want to click on that line says 'FAIL' I get the error message which is also attached.
It was working okay but after 2-3 days when I open FL Studio, it always shows the midi settings and it says 'FAIL' beside the controller name.
