Hi EditMagyar,
Again, I am so sorry you're going through this. I know it's not always easy to tell what's genuine and what isn't, especially given how sophisticated scammers have gotten. Regardless, it is unlikely Adobe is going to give you a new serial key if your old one is not genuine. You can and should try contacting them directly via the links I provided in my earlier response. An Adobe customer care representative may be able to suggest next steps. Perhaps they can also provide you with some concrete proof that the serial number was revoked because it was fraudulent, which could come in handy in trying to get your money back from the reseller and/or filing a complaint against that reseller. If the Adobe representative tries to redirect you to the forum before you get some answers, ask to speak to a supervisor. Although they don't provide technical troubleshooting for older software like CS6, phone and chat technicians are supposed to address concerns about serial numbers and licensing.
You should also absolutely contact the reseller and make a report. If they won't help you, you can look into filing a consumer complaint against that company (Filing a Consumer Complaint | USAGov ). In addition, if you made the purchase with a credit card, you might also contact the card issuer to see if it's still possible to dispute the original charge.
