I'm trying to use the Asus EZ flash tool to update from 0401 to the latest (0608) bios. It won't read the bios from a USB stick (it used to...) so I have to stick it on the root of the C: drive. But when I try and flash, it says "Downgraded File Not Suitable For This System."

Cue me, screaming at it, "IT'S NOT DOWNGRADED, IT'S NEWER! HOW CAN IT BE DOWNGRADED?!?"

Any ideas guys?
