Icharus, today I changed the video card, installed a GeForce GT 610, and the game won't launch. I also tried running it on another computer, even putting my old video card in there, and it runs perfectly fine without any compatibility settings. So, it's definitely not the video card. I still think the problem is with the disks because they stopped launching right after disk D crashed. Even though I formatted it later, something might still be interfering. The games were installed on those disks at the time.
