Um...might I be running into trouble if I'm running RC1? I downloaded this directly from MS. I figured I'd be getting the latest release. Isn't RC2 out?

I only ask because I'm certain I found the proper driver for my controller card here. But when I try to update the driver for that device, it says that it can't find any drivers in the location I point it to. That page specifically states RC2, not RC1.
