auto rudder problems

Hi all ,Can somebody help me fix my autorudder problems . I use the logitech wingman extreme digital and I can`t get my rudder to function. Switching the autorudder on in realism settings doesn`t seem to work..I`ve tried changing the axis from my ailerons to my rudder and then my rudder comes to live but sadly flying without ailerons is a bit tricky. I`ve checked my devices .CFG and there it says that AutoCoor = true so it should be on. Could there be a spelling problem in my cfg file or is there another solution I`m not aware of.I hope somebody can help....Happy HuntingJona
