JOE 4 SHO

thank all of yall for the help i got paid and got a new copy and it works now. i guess the disc had a scratch in a specific spot so it just didnt wanna load. but all is good now

i need help plz. i have tried to play the halo4 campaign. every time i try and load the level it says "playrs failed to load content. a player may be missing dlc" so i had formated my hard drive to get rid of anything that could potentially make it not work. but it still wont load. i can start the campaign new and it works no problem but it wont let me start off were i left off. i have cleaned the disc i also cleaned the lazer lens and still nothing has changed. the only other think that i think it could be is the disc itself. but i have been able to start the campaign from anywhere before but all of a sudden it wont work. also. it has gave me that error message before and i would restart my game and it would work but now it wont..... PLZZZZZ help somebody
