) I had the same PROMBLEM

Just leave your Playstation on for 8 hours or something, but you must stay in the MP menu of WaW. So just don't turn it off when you go to bed.

leave the ps3 on for 5 hours or just leave it on over night and it sticks

so i will probly go to bed at like 1 or 2 then i will wake up at like 11 or 12 and if i stayed in the mp menu were it says find match and whatev it should stick??? kk

leave ps3 on overnight like u said then go into a online game play the game then it will stick
