Welcome to. There is an authentication problem with Rainbow Six Sige. I purchased the product a few days ago. I bought it years ago as a boxed dvd version, but now it didn't work because I thought it was out of date, so I bought it again. Could this be why I am running into the error? I used to have an Uplay account, but it has now been discontinued because of that. I think it's due to inactivity. I don't have many email addresses. Could that be why it won't let me start it?
Hi @HrvthLszlo and welcome to the forums!
The scenario you mentioned can indeed lead to an authentication error. If you purchased the game and used a new email to create a new Ubisoft account, after launching the game from Steam it will still seek to connect with the original account.
