Hey @Hunter_Honk
Sorry to hear you've been unable to launch the game.
When originally launching / activating a game, it will be bound to the Ubisoft account signed in at the time.
If you then later attempt to launch the game with a different Ubisoft account, this error will appear.
If you're aware of an alternative Ubisoft accounts you may
have, please give these a try, as well as verifying
the game's files.
If you still have issues, could you contact us directly via
Support Site, Facebook or Twitter and please attach;
- Any alternative email addresses or usernames you may have used
- A screenshot of the following folder; Program Files (x86)\Ubisoft\Ubisoft Game Launcher\cache\ownership
We will be more than happy to take a closer look and help you recover access to your copy of the game.
Thank you!
- Ubisoft Support
