Hi all, OS: 10.4.6 Halo: 1.0.2 Using a legitimate copy of Halo, I can join/create multiplayer games. However, after I upgrade the core application to any higher version (tried 1.03, 1.51, 1.52), I cannot join/create any multiplayer games. I can see all the other games in my gamespy list, but when I select one and click Join Game, nothing happens. Same thing goes when I try to create my own multiplayer game via Internet. When I revert the core application to 1.02, everything goes back to normal. Has anyone experienced this issue? PS: My original Halo CD has been inserted in my mac. TIA.
