Original Post — Direct link

Whenever I try to start Rainbow six siege from steam the game says "there was a problem authenticating the ownership of this product." And it has been saying that since 2018. Idk what to do. I´ve only played it when I got it on the day. The next day it was saying that. And since that, I´ve been trying to fix it but I can´t.
