Disgaea 3: Absence of Justice [BLUS30181]

I did that with (NisGraphics.spu.self) and recieved NisGraphics.spu.elf in same folder, what's next ? Cause just run the game and still got that error ?

* openModules: ERROR! exit. (ret=0x88000002, file=NisLib/NisMovie.cpp:453)
* _NisMovie_Open: ERROR! exit. (ret=0x88000002, file=NisLib/NisMovie.cpp:794)

Rename the file you recieved, NisGraphics.spu.elf, back to NisGraphics.spu.self (and therefore replace the old one, make a backup first, I didn't do this, and can't easily be bothered to get the file again off the disc to test myself) and run the game. That error is unrelated, and will persist.
