Since the /uploads/ folder was getting rather large and cluttered on FU, I have taken it upon myself to sort the files in it.
This will have no effect if you use or used links to your maps on FU in this format:
http://www.fileuniverse.com/?page=showitem&ID=783
However, if you gave the "Download" link to your map like this:
http://www.fileuniverse.com/?page=downl ... zip&ID=783
or like this:
http://www.fileuniverse.com/uploads/GreenIsles_v2.zip
It will not work, so you'll need to edit your links.
The moral of the story? Always always always link to the map's page itself, and don't hotlink :)
