Plutonium

Look, I installed the base game, then downloaded the plutonium and from there I look for where I put the game and everything works out fine, but when it comes to entering a server or creating a custom one, I give it start but when it is loading the screen appears black and it takes me out, but I don't get an error or anything

Yes, I already tried on all the maps and it takes me out, it is loading, the screen goes black and it takes me out

The game opens normally, when I try to enter a zombie game either online or in custom, it appears that the map is loading, but it takes me out and I can't play, I have already installed everything the game needs but it still takes me out
