I do not know if this problem is involved Xbox Live, more before, up to version 0 .14, the host himself who is sharing the access point could enter in the world, but it seems that now ... It states that another cell route the access point for other players to play, I'm sorry encomodar much, just wanted to play offline with my friends via LAN, if they can not do anything, I understand ... Thanks
