Hiya, cheers for the response, I copied an image of the card, and put it into a new one, but same problem, although I have noticed that if I leave the amplifi on (even though the lights are blinking and it can't be used) for about 10 minutes, then try again it boots up(!?)
Maybe it only works when it is warmed up, could try and convince myself it's a valve amp, and the valves need "warming up" prior to using.
Cheers, like yourself I'm decidedly underwhelmed with the reliability, and will think again before purchasing anything by line 6
