Query: Worse than no calibration (on windows, anyway)

I've tried this on two different Windows computers and ended up less happy with the colors than I was before attempting to callibrate. Light grays look pink, medium grays and browns look green, some skin tones look gray... My monitor may have a bluish cast, but at least it's consistent. Allowing it to adjust based on ambient lighting adds even more wackiness that I can't even describe. I uninstalled it and will not be using it again.However, a friend used the same device in Linux using different software (Argyll CMS, in particular) and it looks quite nice. So if you're using Linux I guess this thing is fine, otherwise get something else.
