Hi,
I bough Rainbow Six Siege last night on Steam - after it downloaded overnight all day today when UPlay launches it says 'there is a problem authenticating the ownership of this product. I reinstalled Uplay twice already, the same is happenning.
Any idea?

Thanks!

@ mooseairborne, you will only receive this error message if you are logged into the incorrect Ubisoft account.

Please ensure you are logging into the correct account.

If you continue to experience this issue, please create a case on the support website.

It's possible there's another Uplay account the game was activated on, have you been able to open a support ticket?
We'll need account info from you so we'd be unable to assist further in a public forum

Hey HenriqueFO_!

This issue usually occurs when you're logged in on a Ubisoft account that the game hasn't been bound to after activation on Steam, you may have more than one Ubisoft account. To determine this we need to take a look over your existing Ubisoft account(s) which we cannot do over the forums as we need to obtain some account information from you. Please head here and create a support ticket so we can investigate this for you.

Hey Thomas,

Sorry to hear you are encountering an authentication error.

This particular error message only appears if you are trying to launch the game from an account that does not own it.

You need to make sure you are logged into the correct Uplay account for it to run.

Hello!

Purchases are linked to a single Ubisoft account and they cannot be shared, therefore it would need to be purchased for each individual account that wishes to play the game.

All the best!
