I just got the game on steam. I had played a couple games of multiplayer with no issues before this problem. When I try to start multiplayer the evening that i bought it, the game launches, the screen goes black, but nothing on the screen loads. Just my mouse. When I alt-tab, the game isn't responding.
Things That i have tried
-Uninstalling and re installing the game (multiplayer and singleplayer)
-Verifying the integrity of the game cache (for both)
-Uninstalling and re installing steam
-running both the game and steam as administrator
-changing the date and time. (this was some peoples solution)
If anyone has any other suggestions please let me know
Two important things i forgot to add:
-All of my drivers are up to date
-Zombies and Campain work just not multiplayer
Hey dude. You can try try to verify your game cache and then reboot your PC. Here's the steps on how you can do that.
Hope that helps.
Have you already tried updating the drivers of your PC to the latest updates including the sound card in your PC?
You can also try disabling the other background application. Just to make sure that other programs aren't in conflict when you try to launch the game. You can check this link for the instructions. Disabling Background Applications - General Troubleshooting - Knowledge Base - Steam Support
