You're welcome to take your issue up with Ubisoft for not allowing a true offline mode or way to disable Easy Anti Cheat in single player/offline mode and forcing us to use these methods to keep both our customers from likely being banned for using the trainer at all and/or us to break our strict policy of no online/multiplayer hacks.
