Same problem here
I opened a thread too (http://answers.ea.com/t5/Battlefield-4/Punkbuster-error-0111/m-p/4621615#U4621615)
Let's hope somebody will help us
P.S. check the last message in http://evenbalance.com/index.php?page=support-bf4.php , they speak about maintenance, probably this issue is related to PB servers
