Please help,

Some players have reported that deleting the BF4 folder in your "my documents" folder solves this problem.  However if you do this you will lose all of your settings and key bindings so I recommend that you test this first by cutting and pasting the BF4 folder from the "my documents" folder to your desktop, then try to play the game.  If the error goes away set up your game settings and key bindings again.  If the problem persists replace your BF4 folder in the my documents folder.  

Be sure to come back and tell us if this works or not and we'll try another solution if if doesn't work.

This did not work.

Could this be punkbuster related? 

I have the Killer Network Manager card on my Gigabyte motherboard.  (E2200)

I play BF4 without any issues so uninstalling is not the culprit. 

The only issue I ran into was with Mawarebytes and it was a simple fix.

Try disabling the setting for "Enable Bandwidth Control" in Killer Network Manager and Malwarebytes will run without issue.

That setting could be causing your other issue as well.

Also make sure you drivers are up to date for it.
