Their site looks totally different. Must have been closed for maintenance what you guys experienced. All my files are still there, they just seem to be jumbled all together in a single place. No neat folder structure that I once had. So mabe that's why some links are dead recently.
p.s. I noticed their url structure also changed.
It used to be:
http://hosted.filefront.com/user_name/
But it's now:
http://www.filefront.com/user/user_name
Maybe Neal can let loose some kind of script on the forum that fixes all those links in one go.
