I have ripped my game on my Jtagged 360's internal HDD. For some reason when I go to play it I run into this......

"Warning:cannot save gamer profile. Please reinsert Xbox 360 memory unit to continue. Press B to abandon game and return to splash screen"

So I can't even play it....If it helps I am not online (Since its a Jtagged 360)

Its sounds like your xbox disk reader doesnt like that burn. That usually happens because every xbox is different. Each xbox has its own disk reading level. But do not trash that burned game disk. That is a perfectly good burn but your xbox cant read it. Hope that helps and if it doesnt then i have no clue. Sorry ;P
