Plutonium

I did manage to get the game to open by switching the file, however, another problem arose

None of the DLC maps have any textures and crash whenever I try to start them.

This is the Mob of the Dead map selection, If there is a solution to this fix please link anything.

Okay, I'm not sure what you mean by "game folder while showing the address bar" means but I presume its this:

And the t6path without showing the token (which I also presume is the big string of text right after it says "token")

Hello, I have tried the steps listed in the linked post, and yet they haven't worked. I appreciate your help though, I have not seen a guide listing this solution. However, I might be able to boil down the problem to 2 things

1. I've noticed this whenever I validate the files on Steam:
   
   It always says a certain file is missing, yet no amount of clearing my download cache on Steam seems to fix this.
2. It might be a thing with my PC and its not liking plutonium and or BO2, which I hope its neither of those cause that would mean I can't play Plutonium.

Hello, I know this problem has been reported before, but I'm here for a more definitive answer, I've tried all the methods in previous similar forums, i.e. putting all the BO2 games in the same drive as Plutonium, installing Multiplayer, I've tried verifying the integrity of the files multiple time, and have reinstalled BO2 and Plutonium multiple times. I am lost, I want to play BO2 zombies maps, and I don't know what to do.
Yes I have the Steam Version.
Yes I have played Multiplayer and Zombies
Please if you can, if there's anything I'm missing, tell me.
