I agree, I have attempted re-calibration following their instructions, but I'm not sure I got which was up down or across. So I tried it thinking I could adjust again later, then at the end, over the page, it says you can never try this more than once! Why not say that at the beginning, then I would never have attempted it. I fear that now, even if they ever get round to producing a version that actually works mine wont because of a bodged re-calibration attempt.
