restart your computer

Maybe you should try placing the plutonium folder in your local disk instead of keeping it in program files(x86)

Update your game, here's the link: http://cdn.plutonium.pw/updater/plutonium.exe

Are all the assets located in the same folder?

I don't know what else to tell you. If no one else has a better solution, I would just try re-installing the game...

I recommend making a new folder in your local disk and moving the launcher into that folder. If you didn't do this before the update with the other files, follow the same directions but place the preinstalled files in a separate folder. If the launcher works but the game(s) won't launch, try opening the game settings and redirecting the file path to the folder with the t6rmp info that you previously installed.

When I open Black Ops 2 Zombies I am immediately greeted with a server browser. This makes it a lot quicker and easier to find a game. the only problem I have with it is that when I leave a match, I no longer have access to that feature. Before the update, I would usually just press the escape key and the plutonium menu screen would pop up, but it no longer does this. Is there another way I can find the Server Browser besides restarting my game?
