For some reason I have never been able to figure out, some people are unable to download files at all, while others have no problem. So even though it appeared broken...your map file still exists.
You can contact me directly through Steam,
or report the file as broken again and include a contact email so I can send the file directly,
or try this:
On the file's page, in the Details Tab, I've added an Alternative Download link. See if you can get the file from that link. Either way, contact me through one of the methods above and let me know if that worked.
