Hey! Faced such a problem. My Spider V 20 MKII worked fine, but today when I selected a preset in the Spider V Remote, the program with my AMP froze, the AMP did not make any sounds. I decided to restart it, and after the restart, the lights on the FX buttons turned on and then faded out, it refuses to work and Line 6 Updater as well as Spider remote does not see it, what should I do? Plugged guitar makes no sound. However when turning it on, i tried to hold FX1 + FX3. Some lights appear and it reacts to turning any knobs/ pressing buttons. I can also hear the clean sound of plugged guitar. Please help!
