i bought this game off amazon and it arrived today. had no trouble installing when i got to play vocals lyrics don't appear (have played console versions and lyrics were on screen but not here. also is there anyway to reassign the keys for the guitar. the fret keys are too close together for me and i keep hitting the wrong ones. also i tried signing up for the online and it says the information i have entered in invalid. is the licence i enter the code on the back of the manual?
