Plutonium

@1800Adequate just search for the custom map u want to play, download it and then put that in the bo1 folder. to do that u have to press Windows+R and search for "%localappdata%", from there go to plutonium, then t5 and paste the mod file u just downloaded in the "mods" folder.
Lmk if it works.

try opening the console and type "cl_allowdownload 1", idk if it helps with the problem, let me know

what game are u trying to play?

u have to play lan if ur gonna play with cheats. Nope, there's no way around this, just wait for the ban to end

@Triggatroy18 ?

saw other person with the same problem, u need to update the launcher

already seen that, they won't do unbans

"The “0xc00007b/0xc000007b” error can be resolved using several methods. These methods include rebooting Windows, updating the . Net framework, running the program as an administrator, reinstalling the app or game, or re-installing DirectX."

idk about bo2 plutonium, but on waw u have to open the game as u always do, click on "friends" and click on his name 2 times to join the lobby he's playing on.
