good afternoon, my respects to all I have a problem since a long time ago I cannot enter battlefield 4 it tells me that I have been banned I contacted ea game in chat and they suggested that I ticked punkbuster, I did it but they did not answer me, it is the only game that has given me that problem recently, I installed it again to see if it was an error but the problem continues I explain, I do advertising gameplay for ea game for the new games that will come, I can't understand why that happened to me I already did all the repair protocol, check the registry and the problem continues. I asked my son if he did something wrong with the game and he says no I told him if I discover a trap, my son will go wrong Can you please help me, what should I do? Thank you very much
