You can go to
www.crazyuscoasters.com and there you will find what you are looking for. You have to have winzip in your computer for it to work though. It takes a while to download all of the scenarios (30 CF scenarios and 21 RCT scenarios), but it's worth it. I done it last night, and had the entire game "beat" down to the Mega park in about 30 minutes. Just open them up, and within 10 seconds in comes up and says "Congratulations ......" Try it. It does work.
