Halo 3/Xbox360?

[Humanops]

my xbox360 will load just about everything for my halo3 game but when i go into campaign it will load every mission except the storm (the fourth one) what can i do about this because i have beat the game before and done that mission on my console and this console and the game since i have bought them both unused are about a month old. because im really trying for all the acheivements i have 41/49 and i was doing them all in order than i noticed the level would go from 0% loading to 20 then back to 0 and it would say i failed to load the mission and yet im playing on local with no possible internet connection when i do it please help and if anyone can tell me a website to say where all the terminals are that would be great because i need that acheivement and then to beat it on legendary and heroic im just doing legendary and the point things which i do on legendary with a few skulls on

i think your using a different profile than when you beat the mission. You need to do everyhing on one profile not one console. Also if you are doing co-op. The second player will have different completed missions than you if you beat one mission by yourself . Same thing goes for achievments.
