    Why does it show "Unable to authenticate the ownership of this product"

    I was gifted Far Cry 5 a while ago by a friend of mine on Steam and for the past few days, I have been playing the game just fine I even played it a few minutes ago, I and another friend of mine decided we wanted to play some co-op and when he tried to invite me my account showed that I was offline. So I decided I would simply close the Ubisoft app and reopen it. As soon as I did that I was no longer allowed to play the game because the app "couldn't authenticate that I owned the game". I have no idea how to solve the problem myself, I've even searched for ways to try and fix it such as this one https://support.ubisoft.com/en-US/Fa...ation-Issue-PC but I've found nothing but failure in my attempts. I've sent a ticket over to customer support (which I don't think I sent over to the right department) two days ago and they have yet to respond. I would appreciate it very much if someone could help me with this problem.

    Hi there, the error message you are describing usually occurs when you are trying to launch a game from your Steam library which is already linked to another Ubisoft account. So we can investigate this further can I ask if you could contact us with the information below via our social media accounts on Twitter or Facebook :

    1) an image showing your steam ID which you can locate using the following FAQ
    2) an image showing the proof of purchase which you can find by clicking on your username in the top right corner of your steam client and clicking "Account Details" and then "View Purchase History"..
    3) an image showing your "Ownership" folder which you can locate here : C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\cache\ownership

    To confirm this would need to be a full screen image clearly showing the above information along with, your Steam username and system clock for verification.

    If you do not have access to any social media services or do not wish to send this information via these platforms, you can also provide us these details by creating a support ticket and upload the requested images as advised here.
