Thanks XstollieX, now I feel like an idiot! I'd been trying to update the driver by right clicking in device manger, directing it towards my flash drive and my Asus install disk and it couldn't find them. Downloaded this one and it couldn't find the driver either. But...I opened the file and tried "setup" and I guess it had to install something besides the driver because it's working now.
