LiveSuit stops stays at 0%

[bill hughes2]

I have tried to flash a rom using LiveSuit (1.07 and 1.09) but, although it seems to start correctly, displaying '3 mins to go and 3% complete, it then reverts back to 0% and remains stubbornly at 0% even an hour or more later. Is there anything I can do to cure this? The device manager in Windows shows the device with a yellow exclamation mark and when I try to update the driver it just says the driver is already up to date.
