I've downloaded Roller coaster tycoon 2 from internet, but the trial has finished, and an activation code is required to play the game. I've downloaded no cd and fixed exe files, but still i can't play. When i click rct2.exe, it says 'Missing or in accessible file' or 'wrong disc inserted'.
Is there another way to play Roller Coaster 2, other than buying the game??
