Battlefield 4

Christian my man, what exactly is the error you get?

Does the game not work in single and multiplayer? Or is the problem only in multiplayer?

Could you post your PC details please? (graphics card/processor name/Windows version/etc)

Below is a list I usually post of common fixes:

-Do a repair install of the game in Origin. In origin right click your game and from drop down choose repair install.

-make sure that you've updated your drivers to latest version.
If its Nvidia then go to the Nvidia website and download the latest graphics driver. http://www.nvidia.com/Download/Find.aspx?lang=en-us
If AMD then go to its website and do the same. http://support.amd.com/en-us/download
Choose a 'clean install' (usually in the advanced install options)
If the problem only began after updating your graphics driver then try reverting to a previous driver (again choosing 'clean install)
If using Mantle drivers on AMD and crashing in X64 version then -Go to C:\Users\Administrator\Documents\Battlefield 4\settings and delete the file "PROFSAVE_profile" (or you could just move it somewhere else on your PC for safekeeping).This will also reset keybindings and graphics settings so you will need to do them again when you launch the game.

-Reinstall Punkbuster.
Go to C:\Program Files (x86)\Origin Games\Battlefield 4 and select pbsv.exe . Choose 'reinstall'

- make sure that your firewall/anti virus isn't preventing the game, Punkbuster or Origin from launching.
Also check the quality of your internet connection.

-Run the game as ADMINISTRATOR.
Go to the Origin games folder (C:\Program Files (x86)\Origin Games\Battlefield 4) and find Bf4.exe. Right click it and go to PROPERTIES, then COMPATIBILITY and tick the box next to RUN THIS PROGRAM AS ADMINISTRATOR.
Do the same with BF4_x86.exe as well.

-Disable Origin in game.
In Origin - Application settings - Origin in Game - disable Origin in game

-Run Origin as Administrator
Go to C:\Program Files (x86)\Origin and right click on Origin.exe and go to properties. Then go to compatability tab and tick the box next to RUN AS ADMIN.

-Reinstall DirectX.
1:go to C:\Program Files (x86)\Origin Games\Battlefield 4\__Installer\directx\redist
2:Find file named DXSETUP.exe and right click on it and choose RUN AS ADMINISTRTOR. Install it. It should update your DirectX install.
3: You might need to reboot computer first.
4: try to launch game.

-Reinstall C++ redistributables.
1:go to C:\Program Files (x86)\Origin Games\Battlefield 4\__Installer\vc\vc2012Update3\redist
2: Right Click on vcredist_x64.exe and choose RUN AS ADMINISTRATOR then follow onscreen prompts.
Do the same with vcredist_x86.exe and follow onscreen prompts.
