Glossy Monitor / Vista / Notebook PC Color calibration problems?

I recently purchased a $540 All-in one monitor printer and projector calibrator called the ColorMunki Photo for my HP dv9000 notebook PC which runs Vista. I ran the calibration and now my monitor looks very noticeably worse, 50% gray looks olive colored and pale blue now looks gray meaning that the color temp is off but thats not all. I created a white to black gradient in Adobe Illustrator and it goes from dull white to light cream color to light gray to darker gray and then suddenly (the last 8%) drops from middle gray to black and then ends. I did the same thing on photoshop and it looks more or less normal except for a random band of light cream color. I wondered what this could be a result of. Could it be that vistas built in color management is screwing things up? Could it be my glossy monitor? Do I have a "cheap" color calibrator that i need to take back immediately? Any one that KNOWS about color calibration is welcome to contribute any knowledge you have on the subject.

Well it sounds like you probably double calibrated your monitor resulting in overcorrection. If it is overcorrected typically the monitor will be a little bit more dim and a bit more yellow, and since olive is a mixture of yellow and green, perhaps this is the case. So what most likely happened was that your monitor was already calibrated through the computers video card software which you can access by going into the monitor settings and going and clicking on the advanced button. Turn off the video card calibration profile if possible using the standard unmodified profile. Additionally it has always been my experience that if one wants to do any kind of critical color correction they use either a good CRT or a high end LCD, but not a laptop monitor.
