I backed up my copy of Roller Coaster Tycoon 3 today, and everything was running smoothly, I entered my cd key, then the installation finished, and when I tried to boot it, the screen goes black as if it's going to start, then my computer reboots. Does anybody know why. I've tried getting a no-cd crack, and the same thing occured with that. Nay help would be appreciated. I'm Using a Samsung SW-224B CD/RW drive, with 24X BenQ media. Have not had problems with this media in the past. I made the backup using DVD Decrypter at 1X, and then tried Nero 6, same thing.
