Have a problem with a download

A friend game a scenaerio he made. I have CF/LL. I tried to install it by double clicking on the file. It never shows up. I haven't used any trainers. Any idea what I need to do?
Thanks!

hmmm....
I don't know much about scenarios...
but make sure you drop it into the right file. it should be in your rct directory with the rest of the scenario files. not sure if that'll do the trick tho
