i installed boot camp for games a few months ago and it has been working ok, but now whenever i boot up in windows my mouse and keyboard do not work at all. The lights don't even light up. any ideas on how to fix this or what caused this? I'm running bootcamp 1.3... I installed bootcamp assistant 1.4 but I don't know exactly how to upgrade it without completely reinstalling windows... or do you have to do that with each bootcamp upgrade?
