My gf just bought Guitar Hero 3 with the wireless Les Paul guitar. The thing is that she called me and asked me how to set it up with the Xbox 360. Since I'm more of a PC person, I really didn't know how to answer her. She pushed the Start button to turn it on but nothing.. What should my gf do in order to successfully setup the wireless guitar controller to work with her copy of Guitar Hero 3? She said that the little X on the guitar just blinks and doesn't do anything, but her wireless controller works. She said she has tried holding the button down and pushing it and nothing works.
