Straight from EA, I had PB problems freezes and getting kicked out of servers. This deletes Everything PB related (even what the installer program doesn't delete, allowing for a true clean re-install). I haven't had an issue since doing this. Good luck to you, PB is a real hassle for a vast majority of players.
