Hey, my problem is that the buttons: Save Edit Comp Stomp Mod Delay Cab/A.I.R Tap all the selection buttons on the bottom side of the display do not work! simply the Tune system button does work. Now it can't be that all the buttons are broken, there has to be some other issue. I've bought the device from a friend which had it connected to his computer. At his place those buttons DID WORK. Now can it be that somehow, because he used the editor software, the device disabled those buttons and got stuck in that mode? Also when I try to reflash the USB firmware, it says that it failed to authorize the firmware. PLEASE HELP ME :(
