so yeah every time i press the b button to load from the disc channel i get an exception error. is there any reason why this would do it to me? I have ciosrev14 installed and 4.0 system menu, and it was still giving me the error before i updated from ciosrev13b. I would really like to get this solved because apparantly you have to load from the disc channel to get rock band 2 custom songs working...so any help will be greatly appreciated
