I need to bring something to your attention, I DO NOT RECOMMEND OVERWRITING YOUR PCID REGISTRY WITH SOME ONE ELSES!. This will cause you to possibly be banned from most of the servers on H2V if some one gets banned using the same PCID, and the chances of being unbanned are very slim!
Banning players via PCID is a very common method inside of all of the servertools that people use, even the new servertool that us at H2PC are developing use it.
