Thanks to [SVG] Sparkie951:

"The map would not auto download for my server, received a "Recursive Error". I noticed that the .nav file is lower case "T" and other 2 file names are upper case "T". This may work for Workshop, but it does not work when downloading from another server. I renamed all the files to all lower case and problem was solved. Just a heads up in the future user the Same case for the letters for all file names. "
