Courtney, XPlane uses a new way for downloading: The first download is very small, the 'real' download begins after double clicking on the BitTorrent file (this is the tiny download)

You hav to install BitTorrent first. The link is on the X-Plane - site

it works quite well. Over the Years I have had troubles downloading over and over again - strange, but when I get a server that's running apache, I usually get the downloads perfect, when the server is running some MS-Stuff, it fails. Anybody knows why?
