Bug de la 1.7

Bonjour, comme vous le savez surement la 1.7 est sortie récemment et mon problème et que je crash a chaque fois que je lance une map solo et les serveur recherche une connexion qu'il ne trouve pas !
J'ai bien sur supprimer mon .minecraft et réinstaller la 1.7.2 mais toujours le même bug je suis vraiment perdu :/

Code (cpp):
