Both firewall and Microsoft Security Essential are turned off. I copied the full name details, including email, and the Key number in the appropriate slots. Nothing seems to work; keeps telling me the registration failed. Ideas ? This is a bit frustrating.
Ok, figured it out. I had for vorpX with PayPal, registered to one of my emails addresses, and specified another email address for the actual software registration. This seems to have created a conflict. When I tried to register from the second email, everything worked fine. Sorry for the panic :(
