I thought I should be diligent and simulate this to see what you are dealing with
@Kiwi Rider. Dynojet changed the site since I last remember. While logged in I can select any map and it immediately downloads.
So if you were logged in, looking at a map list, selected one but nothing happened, I wonder if you can check the browser's download directory? Sometimes these browsers do not have a clear indicator that they downloaded a file. Also, the browser file menu may have a shortcuts to its download folder.
Or I wonder if one your browser or antivirus is preventing a download, or it is asking for approval but it is so small on the screen that you missed it. (Happened to me a million times.)
I always change my browser download directories to a common, easy to access folder so that I never have to search for this stuff, for example: c:\downloads.
I do not think I can attach anything but pictures here so I do not think I can retrieve a map file for you.
