Multiplayer Not Working?

**ALMOST **every time I try to connect to a server, it would do it’s regular stuff, download what needs to be downloaded then send server info. After the downloads, there’s like one more bar left on the loading screen then the game crashes. WTF. That’s the worst. It’s been happening A LOT lately and it sucks. Any help?

Yeah you need to upgrade your processor. I have friends who got the same prob, reinstall everything all addons everything. It’s normally a addon interfering.
