If you having trouble with your PunkBuster service aka getting kicked by the server, you should consider updating PB. Our player theevilholy created a good Punkbuster FaQ in the battlefield board. If that link helped, let us know and give theevilholy XP for his work. If not, please reply that we can find possible other workarounds!
I also recommend updating your firewall/antivirus software and closing all not necessary third party applications.
