This is the second CoifD2 game that I have exchanged from wal-mart. Have tried to load this game on 4 different computers, all my machines, and all with the same error message. The 4 machines are all differnt hardware configs, win xp configs, and software configs. It's not the computers. I'm starting to think it's a bad batch of discs from the producer. Any dics inserted other than disc #1 tells me to put disc #1 into CD drive in order to install the game.
