I used 360rev once and it worked but know when i try to load the world, the loading bar doesn't even show up. i am also getting an error whenever i try to edit the gamesave in 360rev save: http://www.mediafire...jpitjfn7b1xp1to
there is no fix for the minecraft.exe has crashed error, i don't know what you have added or done to the save but it is completely unfixable
i made a thread called "how not to mod minecraft" it has a list of what not to add, http://www.xpgamesaves.com/topic/42026-how-to-not-mod-minecraft-360-edition/
