Compaitability issues


New Member
My friend and I are having some issues with a LAN game. He and I are using two laptops, mine being an iBook G4, his being a Lenovo. I used my own two CD's to install the game, same CD Key, and we tried to set up a LAN game (UDP/IP). When I click on his name for the game, I'm given a prompt telling me something about an "incompaitable version" of Starcraft. I don't think it has to do with a update, so I was hoping someone could help me out?

As a final note, another friend of mine and I were playing a game in class, but he was using a pirated version of the game. Would that be anything to do with it?
