'Problem Authenticating Ownership' message
This means you may be logging into the game with the incorrect Ubisoft Account and email address.

Unable to purchase Credits - Steam
Please try toggling the Steam overlay off and on through the Steam settings, to make the purchase -
Settings/Preferences > In-game tab, uncheck the box next to 'Enable the Steam Overlay while in-game'

If you are using a VPN, try disabling this before making the purchase, in case your VPN switches your IP address to a different country.

Next, please make sure that the currency you are using to make the purchase, matches your IP address location and also matches your 'Steam Store Country' which can be viewed here as this can be caused by a regional issue - https://support.steampowered.com/kb_...6#othercountry

Launcher asks you for a CD key
If you recently purchased the game from Ubisoft Connect, Steam, or Epic, the launcher should not ask you for a Steam key and should instead automatically bind the game to your Ubisoft Account.

Please try signing out of Ubisoft Connect and whichever launcher you purchased the game from, clear the launchers cache, then make sure to sign in with the correct Ubisoft details.

If you purchased the key from another retailer, please send us an image of the key from the retailer you purchased the game from, through one of our support links below and we will check what Ubisoft Account the key is linked to, in case you forgot your login details.
