The new Battlefield 3 September 4th Language fix is now available. Confirmed to be working by multiple people.
How to install the new patch:
First, Simply start Origin and let Origin update your game to the latest version.
Complete a Repair Install on BF3. THIS IS A REQUIRED STEP. It will not re-install
your game, it simply verifies that all files are in working order. This is an important step or the patch will not work.
ONCE THE GAME HAS BEEN UPDATED TO LATEST VERSION, download the languag
e files from one of the below download links and place it into your installation directory. Be sure that you've already completed a repair installation on BF3! Or it won't work!
The game should now work. If it doesn't, right click the game in Origin and select to complete a 'repair install' (It doesn't install the whole game, it just updates the language files within a few seconds)..
Origin will apply the language files to your installation and your game will begin working.
