I downloaded two ISO files, CD 1 and CD 2 for Sim City 4000.... I used WinISO to extract the files rather than burn them... since I'm low on CDs... I run the installation... but then it says... please insert Disk 2... what do I do now?... I have the extracted files for the 2 CDs in 2 seperate files... how am I going to be able to install it... or should I just burn it on a CD?
