Whenever I have a problem with a CH product and contact tech support the first thing they tell me is to start Control Manager and check to see if your stick is calibrated and responds correctly. I suggest you try that.
If all that checks out, then your stick mapping in AH2 has gone away (or never existed). BTW, six months ago AH2 was not released. That is most likely why you are seeing no mapping. I don't think the settings and mapping can be ported from AH1 to AH2, but I never tried.
