I am getting an Error u99 after a power loss at my home. I have tried to unplug and reset my setup and still the u99 appears the next morning after an attempted Guide download. I also downloaded the firmwear update, but my E-85 fails to read the disk. I made the disk useing Windows XP media edition. Can anyone give me any help on this problem or has anyone experienced the same or simular problem? I also failed to mention that the guide does not download after getting the U99 error messages.
