"Setup Needs the Next Disk" ???

[xBRIANx]

Hello, I just purchased CivIII and triend installing it on my computer. I meet the sys requirements with no problem. However, when I click FULL INSTALL, it gets through 70% of the installation, and then prmpts me, "Please insert disk 2 that contains the file Sounds\build\ancient\AncECfull.mp3" ...I click OK but it keeps repeating itself. Finally I click CLOSE and the setup exits.

I've also tried the Minimal Install but it won't run at all when I click Play CivIII.

Any suggestions? Thanks!
