RE : Interfacing FEZ cobra

I have recently tried to update the firmware on my FEZ Cobra, and now the screen has turned completely white, and I am unable to update using EMX updater and I am also unable to update manually. I have bought a high end mini USB, but I am still unable to get a response. When I Ping the device on EMX updater there is no response from the device. When I look on device manager, the device is present but there is a yellow exclamation mark next to it, which as I understand will indicate that something has malfunctioned? Please Help! Thanks you!

Is this a duplicate of the other post in this thread http://www.tinyclr.com/forum/topic?id=9133 (ie did you forget your user name?)
