bo2 multiplayer and zombies not working (help)
-
so i just downloaded the game 2 days again and it worked fine. today I opened the game and when I went to online it showed "connecting to online services" so I waited for about 5 minutes and nothing happened, so I just joined from the home screen (using f10) and I joined a server but as I was joining the server it like froze and got me back to the home screen saying "challenge verification failed" and the frames dropped to about 1-2 fps as the notification showed and i couldn't really do anything so i shut the game and restarted it but after restarting the same thing happened after some more attempts doing the same thing a notification popped up saying "UI error 7562" and i tried starting bo2 zombies too but again the same thing happened does anyone know how to fix this i really love the game and want to play it
