I was not using any cds, i saved the contents of those 2 cds in the hard drive in a single folder so i could have a backup file in case something goes wrong or i lost my cd, then I will have to install sim city without the use of the cd, instead i'll be using the backup file, but the problem, when i tried installing it from my back up file, it still searched for my 2nd disc halfway the installation process, i clicked ok when that pop up "insert disc 2", nothing happened,
