My kids received this game, Roller Coaster Tycoon 3, like a year ago for christmas. Unfortunately our cpu at the time didn't have enough memory to run it. Now that I have a computer that will work, I cannot find the code you have to enter when you install it. Is there anything I can do? It would seem silly not to be able to use this! the part number on the disk is 25655cd, on the box is 25655j.

If you still have the box, the code should be somewhere on there, or on the CD case. It looks like six groups of four characters, like this (not my actual code):

****-****-****-****-****-****
