Plutonium

I downloaded Plutonium just the other day, both IW5 and BO2, but a new update dropped and now i can't play the game, and I really don't feel like downloading both games again. I get this error everytime i launch plutonium:

I've tried launching as administrator, diasabling my antivirus but none of those have worked.

RajerThat try updating or reinstalling direct x. It worked for me.

AEArcticYT Hasn’t worked. Idk what’s happening

I’m trying to get into a game of multiplayer on BO2. But everytime I pick a server and get into the loading screen, it says on the top right, “EXE_SERVER_DISCONNECTED”. It’s on zombies and multiplayer so I can’t play anything. I’ve tried reinstalling it and turning off my firewall but nothing has helped

RajerThat I’m having the same problem. I pick a server, is goes on to a loading screen and I’m the top right corner, it says something like EXE_SERVER_DISCONNECTED. And when it puts me back on the main menu, it says Server Disconnected
