I bought GTA IV from steam a couple weeks ago, and i have a problem, i can't go multiplayer. i enter the game, bring the phone up select multiplayer, and i get the message "You must be connected to Rockstar Games Social Club to play multiplayer". I don't really know what to do anymore, when i login to RGSC site it's fine, i have stats and achievements updated, bun in the game i can't access multiplayer.
