Hello guys. How are you all. Well stuck up in an issue. Would be great if someone can help me out. I have completed installing the portal 2 game. Now, I wish to know whether portal 2 is able to run on bootcamp. Hence, I downloaded and installed the game. It does install my save games and all. However, issue arrives whenever I try to start my single player. I am able to see a loading screen which says steam validation rejected. Guys please let me know what the issue is. Thanks.
