Plutonium

There are three of us in BO2 Zombies. I can join Friend #1's lobby and get into a game and Friend #2 can also join Friend #1 and do the same, but when it comes to me joining Friend #2 and vice versa, it doesn't work. Why? And is there any fix to this?

HannesC Okay I was waiting for it to happen again and when I tried entering vid_restart nothing happened. I still can't alt-tab back into the game but I can still hear the audio from the game. My friends in the game are still playing and I'm the only one that can't get back into the game.

ScythePods I just noticed its the same for Multiplayer nooooo

When I try to join a friend's custom match, the game crashes automatically ( I think this is happening to everyone right now as well )

Every time I play BO2 Zombies, whether I host a game or I play with my friends, it always crashes mid-game (maybe around Round 6-11). First, my game freezes and after 2-3 seconds my game goes to black. My friends who are in the game are perfectly fine, but I can't alt-tab back into Plutonium to play the game. Can anyone help?

coder x64 Thank you so much, it worked perfectly.

These two files are what my friend is missing (and what the creator of this post is most probably missing). By the way, when pressed "OK", these two error boxes pop up twice. We have tried disabling the firewall on Windows but it didn't do anything. We are thinking that we most probably have to download these files or something like that
