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!
Please keep in mind that some severs having special rules for use of weapons or several other game mechanics. It can be that you are kicked from a server because of use of a special weapon or other server restriction.
I also recommend updating your firewall/antivirus software and closing all not necessary third party applications.
