USB issue since upgrade

Hey Guys,

I have just downloaded the new Apple Firmware and now I have copied the ATV files and installed them on the USB but I just cant seem to get Apple TV to boot into the ATV Flash section when I reboot and I have tried two different flash drives all of which worked with previous versions. Any suggestions?

Interesting resolution.

I normally create the drive on my 64bit Windows 7 machine but tried using my 32 bit Windows 7 machine and that appears to have resolved the issue.
