My Line6 Relay10 is 1 week old, the charge out of the box finally died and now it will not charge. I have it plugged in for days and it just blinks RED. I downloaded the updater onto my Mac but now I have no idea what to do next? Why would the downloader not include any instructions....So after reading here, I have my relay plugged into the USB port and have tried all 4 USB jacks and 3 different cords, including the brand new that came with my Relay, and nothing happens at all? My Mac will not recognize this thing. Not even sure why I need to update firmware just for this thing to charge but I cant even get the firmware to work. Probably should just return this while I still can buit it worked so well before dying...So How do you actually update the firmware and why is my Mac not recognizing the device?, I need step 1 if anyone csn help.
