ok, got a MAJOR bug here!
playing rockstar mode on hard setting and the key's won't respond to the frets coming down the screen. you can see that the frets gets pressed, but the game won't recognize them.
gonna try refreshing the game though and see what happends..
 "Santa Rockstar: Metal Xmas 3"){kind=icon}
