Salut.

J'ai installé le mod SPC pour un monde mais lorsque je vais sur mon monde ce message apparait:

Minecraft has crashed!
----------------------

Minecraft has stopped running because it encountered a problem.

J'ai essayé de backup minecraft.jar , mes mondes mais rien n'y fait!

Quelqu'un pourrait m'aider S.V.P? Merci
