Flies Offline Activation (Assassin's Creed: Odyssey)

Good day all I will say in short, know how to do and operation of the activation problem happens on my friend's car (and I don't mean -_- )... so it worked out perfectly, got the latest version of the game stood DLS, ALWAYS run exclusively OFFLINE and once a week +- stable sometimes - could Not start the game. Check if there is issues with installing the game....
And requests to go ONLINE, have him re-do the activation and for a week Yupley calms down, then again damn... is fed up.
Declare with confidence that the run(Yupley) exclusively through the matches from, but what's the damn problem?
It is precisely in this Assassin with the origin of such events.
Thanks in advance.
