My version of Minecraft on the Xbox 360 has stopped working properly. All my other games work fine and there is no problem with my network connection. When the game loads to the menu screen, all is fine. But when you try to load a game or even start a new one, the game screen gets darker and once you are in world, the only thing you can do is move forward. I have deleted the game and redownloaded it in an attempt to fix it and have also deleted the additional add ons purchased. Nothing has worked and I need help.
