Problème Minecraft

Bonjour,

J'ai un problème pour jouer à Minecraft.
J'ai installer tout ce qu'il faut pour y jouer : textures packs, sounds ... etc.
Mais quand j'essaie d'entrer dans le jeu (en ayant mis un pseudo) la page de démarrage Minecraft se ferme et je reçois un dossier où il est écrit ceci :

#
