Hello. Im Seunggyu Cha(SG for short). I have guitar hero live for wii u. I got brand new, sealed one from my friend as a gift. But it is not working. I dont know why but it doesn't seem like mechanical problem. All the buttons are working fine. But i cant even pass tutorial. Even if i press the buttons nothing happened. I know how play it and Im pretty much good at it. sometimes i play same thing in game center. It might be system problem (not sure though) . Also i googled about it and i don't think the problem is not only my problem. I hope that you guys have a solution Thank you.
