Help with Project M stages

[Shartimus]

So i tried to replace the Project M's Final Destination but when i try to launch the P:M a weird code appears on screen and then it freezes, and no, it's not the same code to launch the Twilight Hack, but well can someone help me with that?, the only thing i do is replace the files that i want with the P:M ones but for Final Destinantion do i have to replace something else?
