Game Won't Start Up

[PWNdelaPWN]

So my friend recently bought the game and i played a few matches with him. Then one day his game won't open he presses play and it says preparing to launch then it doesn't open. He has tried to re-install, verify his game, and updating directx. Its kind of a shame because he was looking forward to playing in events and now the game won't open. If you could help much would be appreciated.
