Updated authorization codes.
The Good News:
Your registration code is now linked to your physical computer hardware. This means that that you will no longer have to request additional codes for other user accounts. This also means that the authorization code should still be valid after you wipe your hard drive and reinstall your OS.
The Bad News:
All currently registered users will have to request new codes after installing this version!
Believe me, this is as hard on me as it is on you but hopefully this will simplify things in the long run.
