The message you are receiving is not related to the authentication key I dont think.

If you are on Vista/Windows 7 try reducing the User Access Control setting and see if it then allows you to run the launcher.

If your authentication key has already been claimed by another, then you should contact Amazon and/or Accounts & Payment Support

Calls are free from landlines if your country is listed or use Skype to call the UK number for free.
