Plutonium

Edit : Discord says I'm playing, so maybe I have to type something in the console ? Can someone tell me ?

So I installed the launcher and Black Ops 2 and when I tried it, it happened to have this infinite loading time when I try to launch BO2 in multiplayer.

I firstly thought about a corrupted file because this file on the screen is in the FAQ in the corresponding section.

So I repaired the file using the "Repair your files" topic. After that, I re tried to launch the game, leading me to an error because he couldn't connect to the server. I followed the topic about that, changed my DNS and tried again.
It leaded me to have another time this infinite loading time.

Also, I'm not using the Steam files. I'm using the plutonium version that I downloaded from the website.

Does someone have a fix for that ?
