well the fact that i've gotten 3 discs (and the same problem, cant get any of them to work) and none of them are scratched and my xbox 360 is in mint condition crosses out all but one of those suggestions.
Hmm, it might be the installment, I really hate to say it.
Do you dashboard log out? Or shut down the right way?
If you cut off the system, dashboard log, etc. It currupts files over time.
If it keeps happening, delete the whole FFXI game from your 360 and re-install it.
It wont delete your character or anything, just make sure you have all your information.
