I have cod world at war, i havent used the 2nd controller in quite some time, when i plugged it in, it began to work, i play about 4 hours on a 2 player mode and all if a sudden it went haywire on me, it kept shooting and reloading by itself and then it just stopped responding. the only thing that works on it now is the ps symbol in the middle and the D PAD, can someone please help i would hate to have to buy another one.
