If you are running Windows Vista, the last I heard, (and tried) is that Ch control manager is not compatible with Vista. Just my .02 cents worth.
While awaiting parts for my new build, I was using my sons box, which had Vista home premium. I had trouble with my CH stuff, then I couldn't figure out why I couldn't get my AH map to work on the Control Manager. The forums at the CH site advised that Control Manager was not yet compatible with Vista. That was a few weeks ago, so take it for what it's worth as of now.
Alot of good info at the Ch forums.........
Good Luck, it was driving me nuts not being able to use the CH CM. Old habits hard to break.
I also found that the CH gear was more apt to be a bit "spikey" and less precise by using only AH calibrating, and not the CH CM and AH calibrating and scaling. Just an amateurs opinion.
