Hello gamers. I have been trying to start playing GTA IV again, so I used STEAM to install it.
It installed the Rockstar or ...maybe it's the GTA IV social lounge, so I thought I was ready to go, but it gave me errors. So I started using the only tool that matters, Google. And I found out I needed to install the Games for Windows Live software, so I got it, and signed in. But... still I am unable to launch the game. The Social Club won't even allow me to sign in, there is no option to sign up. Here's a screenshot

and if I press Play, I get this error.

I am tired of reading the Steam forums, even though many people have this issue, I wasn't able to find a fix.

I am using Windows 7.

Thank you
