Hi Peter,
I haven't heard of our CDN being called "highwinds"--are you downloading X-Plane 10 from Laminar Research directly? The digital download speed is determined by your internet connection. We recommend downloading only a little bit of scenery at a time in order to get flying as quickly as possible. If there is a time out, the installer should keep going unless the internet connection is dropped entirely. Please attach a copy of the X-Plane installer log.txt & explain what you are doing step by step and be as specific as possible.
