Re: After the update by the end of February, you can not log into the game.
Hi, here are some things to try:
-Read this post from eabastien http://answers.ea.com/t5/Battlefield-4/WORKAROUND-PC-Recent-crashing-issue-workaround/td-p/2405963
Do what he suggests and see if it works.
If it doesn't work then...............
-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)
-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
Right click on Origin.exe and go to properties. Then go to compatability tab and tick the box next to RUN AS ADMIN.
