edit sorry meant to make question first post on forums

You are using the GOG version? I believe that you cannot register right now because the servers are down due to them making a new Witcher website that will also have Witcher 2 info. However, there is no need to register the GOG version because it is already fully patched.

Check out this thread about registering:
