Bill and others,
I've just made the directions for downloading the route files a little more prominent.
To download the route files, you need to "right click" on the description of the file you want to download. Then select "Save Link As.." from the dialog box that pops up and the file will be downloaded to your computer. To confirm I've just tried this method and it works as intended.
Hope this helps for you. Let me know if more or different directions are needed.
