Problem PLZ Help !

EVerytime i play p4f it close after a match why ?

because your probably hacking, if not then it has something to do with your web browser, just download the latest version of your web browser. IF that does not help reinstall your BFP4f files.

It used to happen to me also when i used google chrome! so i switched to mozilla firefox! if it doesn't work then also then search in the bfp4f forums! if u don't find any solution then u will have to re-install ur game as @marijuana says!
