I just bought the game a few days ago, and I can't get into multiplayer. It tells me 3-4 times that I can't connect to other players in free roam, and then freezes my whole system. I have a great connection, and have ZERO problems in any other online games. What is the deal? I either need to be able to play, or I need a refund, because the game isn't working. I would prefer to be able to play. Does anyone know how to fix it?
