I just bought and downloaded GTA IV from steam but it wont work. Once i launch it i am asked to sign into social club and when i do it says login successful and then closes the windows and does nothing. I have downloaded games for windows marketplace but that didn't change anything. It seems that GFWM doesn't detect the game because nothing shows up when i open it. this could be because all my steam games are stored on a separate drive. Any help is appreciated.
