i got a global ban from pb

Hi,

what are my options here, please advise? I got the same problem and received this reply from Even Balance people

Note #2: The supplied GUID has been associated with hacking or interfering with the normal operation of our PunkBuster software and has therefore been compromised resulting in a global ban from PunkBuster enabled game servers. We have no way of knowing who was actually playing with this GUID at the time the violation was triggered. We also have no way to know if the violation was triggered on your specific computer. Our system does not collect personal information and furthermore we have no way to attach a cheat/hack violation to a specific person. This ban will not be lifted as then the person who did trigger the violation would again be able to join PunkBuster Servers using this GUID.

To be clear: we are not saying that you cheated as we have no way to know who triggered the violation. If it is certain that no one playing on your computer ever had a cheat/hack violation triggered by PunkBuster, then your GUID (cdkey and/or game account password) has been stolen by or leaked to someone who has used it on a different computer to trigger the violation. We do not have the means to help you find out who is responsible for compromising your GUID.  

Since I`m the only person that uses this computer obvious is that my cdkey (or else) is being compromised.

Hoping that we will resolve this fast.
