Someone burned a copy of Sim City 4 for me, but when I try to play it, it say Please insert the correct CD ROM. I tried taki9ng the exe file in thecrack folder of disc one and overwriting the one on my HD and now when I try to play the game, nothing happens. I have also tried downloading file to overwrite the exe file and Sim City 4 started, but whenever I try to go into a city, it closes. Is there any files I can get or use on my HD to play the game? Thanks in advance. I don't know much about computers.
