Hi there! This is Virginia O.

I understand that you are experiencing issues with your Assassin's Creed Iv not working.

I apologize for the inconvenienced this has caused you. I will do my best to help you.

Please uninstall the current version of Uplay from your system.

DmC Devil May Cry

Legend of Zelda Link Between Worlds

Assassins Creed IV Blackflag

Grand Theft Auto V

Animal Crossing New Leaf

and call me crazy, but Aliens Colonial Marines.

Those are my contenders so far, but I still have a few more to play on X1 and PS4.

Indeed, I know that it's regarding Assassin's Creed IV Black Flag, when you buy Assassin's Creed IV Black Flag - Season Pass on Xbox One version it will not work on Xbox 360 because there is a version for Assassin's Creed IV Black Flag on Xbox 360 console and Assassin's Creed IV Black Flag for Xbox One. Those two are different.

Well i have tried many games like far cry 3, assassin's creed IV, call of duty black ops, and many more but they all got the same error. Currently i am trying to play far cry 3. Games like gta V, assassin's creed origins and watch dogs 2 run perfectly.
