aparte se me demora demaciado en entrar a la sección

Para que al final cuando entre quede así

Pero cuando juego desde la 1.7.2 hacia abajo ( 1.6.4, etc) me corre todo normal, juego offline, multiplayer. Si me pueden dar alguna solución para poder jugar en su servidor, les agradecería muchisímo.
Un saludo.
