if you installed the game you USED the activation Key
Activation Keys are only good for 1 use after that you access your game by logging into your Uplay account
you can not use a Uplay activation key more then 1 time

Uplay PC CD keys are unique and can only be used once. Once they are used, they are bound to the Uplay account that was logged in at the time of initial activation.
You do not need to create a new Uplay account. If you are receiving this error, chances are you already have more than one Uplay account. You can simply log in to your other Uplay account(s) to find which one has the game registered.
If that is happening to you, then you should directly get in touch with our support team.Originally Posted by Duecallion Go to original post
