keeps going back to title screen

its been 3-4 months since i played halo 4, i start up the game and NOTHING STARTS i start up a game in war games it goes back to title screen start up spartan ops same thing custom game does the same thing to, tryed my DLC what a surprize it does the same thing, while doing this i realise why i stopped playing, now right now everyone think i have a bad disc incorrect DLC doesn’t work either and i used to play halo 4 alot im a rank 129 which sucks i want that max rank. before i started playing again i did everything suggested remove my profile redownload dlc, reinstall disc 1 and 2 clear cache ect. also upon launch i got this game one of the maps i was really looking foward to which is longbow didnt work so i have never played the map instead it would studder the loading screen and send me back to the title screen. i have read other forums posted a few month ago so i thought i would start the problem back up

is anyone else having the problem and have the found a way to fix it
