I have had Civ4 for a while, and installed it on my desktop computer (where it worked great). I recently got a new laptop and the desktop is going to be gone soon, so I was going to have to play Civ4 on the laptop. I installed it and the installation process had no issues, so when I switched from disc 2 back to disc 1 to play the game, the autorun came up like usual and I hit play. The loading page popped up like usual, then it just stayed. It never progressed to the part where it loads the XML and Python script and the resources, and after about 30-40 seconds, the message popped up saying it couldn't locate the CD-ROM, except I had the correct disc (Disc 1). I took the same disc (to make sure it wasn't the disc's problem), and put in the other computer that had Civ4 installed, and it worked just fine. Do you know what would cause this? It doesn't even seem to be a system requirement issue (which I'm pretty sure all requirements are exceeded), because it just won't read the disc. I know the right disc is in and nothing is wrong with it, because the game installed just fine, and it works fine in my other computer, does anybody know how to fix this?
