First let me say welcome to the forum. Which registration key are you talking about for the Home Edition or Professional Edition? Which ever version you requested a registration key for don't worry you are still fully protected as both are fully functional for 60 days. I would also reregister again but with a different email and see if you get the email with the registration code. You can also send an email to support@asw.cz with the information you used to register that should help you. If you need anything else please ask.
