Re: DirectX Error
-Do a repair install of the game in Origin. In origin right-click your game and from the drop down menu choose 'repair' install.
-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.
-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)
