Kicked by PunkBuster: No idea why. (PC)

I've been getting kicked by PunkBuster all day. No idea why. I checked Battlelog and it said "Game disconnected: you were kicked by PunkBuster. Stated reason: PunkBuster kicked player 'Niveleur_XIV' (for 0 minutes) ... RESTRICTION: Service Communication Failure: PnkBstrA.exe" No idea what it means. No idea how to fix it. I've tried installing punkbuster and it's just a massive pain.
