I put a simcity 4 disk into my computer, but it won't do anything. I can't run the game, or install it (i don't remember if i have it or not) and i just want to play. I'm using a Windows 8.1. It's registering that the disk is in, but even forcing it to start won't work. It might just be obvious, but the disk i'm using says Disk 2. Am i supposed to use Disk 1? It's also old, so that might be a problem as well.
