BO2 Zombies Crashing

[tuccineo]

Hello,
I've downloaded the game with the piry.exe a few days ago, and since that day i tried to play BO2 Zombies on all maps, but a non-sense bug has fuc*** my gameplay.

Starting at the time that my game close in the middle of a zombie play, whatever the round or server, he just quit to the desktop without any sign of a crash dump or error.

I already tried to re-install the game and other possibilities like use a vpn, but, nothing.

Please, someone might help me?
