I have WC3 installed on one of my computers, but in order to play it, I need the CD in the drive. Unfortunately the CD was damaged by one of my kids (they won't admit which one did it!), but I do have a backup ISO image of the disk. I burned that to a CD, but that didn't work, so it looks like I will have to buy another disk. Is this correct, or will Blizzard send me a new disk if I can prove that the one I have now is damaged?
