All right, my razer is plugged into a USB port currently. The mouse works, but when I install the new XP drivers and go into the razer configuration thingy, nothing that I do in there effects the mouse. For example: If I change which action is assigned with which button it does nothing, and the "On-The-Fly-Sensitivity" does not work, something that I desperately want to use. Anyone know what could be wrong?
