I don't think any of those download links work any more.
Is it easy to set up the scenario yourself? I cannot find any helpm file that explains how to do it.
I do them all before playing. Just have the first player setup the map and his stuff, and then mail it to the second player to setup. If nothing else, it helps ensure that both people know exactly what they have and where. Most scenarios have enough variability in how they can be setup that little is gained doing it ahead of time.
