Zombies not launching

[zeliza]

Multiplayer works just fine, but whenever I try to play Zombies it'll launch the game with the title screen frozen and then everything crashes a few seconds later, no error message or anything.

If you're using your steam game files, do you actually have zm files downloaded?

Also, I'm guessing you're launching t6zm from the launcher and not the ingame menu, correct?

Yep I have zombies downloaded, I can play it just fine without plutonium.
And yes, I'm launching it from the launcher. Also tried doing it through PL BO2 in-game menu, but same exact problem.
