The key for the 5th Anniversary Edition is located on the back of the game manual.Â The CD-key can be used to do only one of two things.
1. It can be used to create a brand new account with access to all of the game expansions to date, including Labyrinth of the Minotaur.Â After installing the software and launching the game, you would click 'New Account' at the login screen and enter the CD key when prompted during the registration process.Â You will receive a 30 day trial period for your newly created account.
2. It can be used to upgrade an existing account and unlock all expansion content to date, including Labyrinth of the Minotaur.Â After installing the software and launching the game, you would log in to the account management website using your master account username and password.Â Click on the Activate Key button and enter the CD-key as prompted.
When you use the CD-key to upgrade your account,Â 30Â days will be added to yourÂ current subscription period.Â If you are upgrading a closed account, you will need to first payÂ a normal subscription fee to re-open the account.Â Then, when the CD-key is used to upgrade the account, 30 free days will be added to the subscription that you just purchased.
Please note that once a key is used, it cannot be used again, nor can it be de-activated.Â A CD-keyÂ is permanently attached to the account thatÂ it opens or upgrades.
