RollerCoaster Tycoon 3 back-up not working
 

the game installed fine and everything but when i go to play it, it says please insert the Rollercoaster Tycoon 3 disc. Is their protection on the original disc? How do i fix it?


thanks in advance for your help.

What program did you use to copy the original?

i used nero

Don't use NERO to make 1:1 copies.
Try it with CloneCD or Alcohol120% !!!
