I bought the game today (nostalgia, you know the deal). I bought it from steam. As soon as I launched it on Steam, the game key was displayed and I was directed to the Ubisoft Launcher. I activated the key and now I have the game in my library but I can't launch it. The start button is grayed out and the only action I could do is go to support. And here I am. How can I start the game?
