BF2 question.
 

Hi, i know its illegal to ask about serials but its not a question about requesting a serial.. well the situation is me and 3 of my friends bought 2 cdkeys and we all 4 using these with key changer.. but the thin gis its taking soo long to check if one of those cdkeys are in use or not so is there a way to check for cdkeys in use or not easily? mabye a small program or something do u know ?
Thanks..
