When I launch Grand Theft Auto IV from Steam, and press to Play in the Rockstar Games launcher, it says: Social Club login failed. Please try again.
But when I do so, the problem doesn't go away. I haven't changed my account details since last playing and I can access the Social Club site just fine.
Could it be related to Games for Windows Live turning into Xbox for Windows Games?
I had seen a lot of people on the Steam forums with the same issue, but no answers there.
