Hi, I have a 2.0ghz unibody macbook, and i installed windows xp on the boot camp partition, installed drivers, up until here everything was working fine.. i decided it would be a good idea to upgrade to bootcamp 2.1 and then suddenly the boot camp icon in my system tray went away, and so did the nvidia panel (yet i can find them when i go to sys. prefs.) and the sound no longer worked.. now im stuck and i have no sound. I tried reinstalling the drivers using the cd and it still doesnt work.. also when i remove my headphones there is a red light coming from the jack.. how do i get my sound back???
