I had the same problem with Tripod.Lycos. The community at Alice.org (a site for the free Alice animation program) didn't have an area for Alice Object Files, so I made a free site with some 3dmax converted objects for people to download. For some reason, you couldn't download the files, and I figured that it was because the file extention was unknown to them. You'd think that they would just let you move the file "As Is", but it didn't work at all. The funny thing is that it DID work the first time that I tried it out, but as soon as other people got around to it, it had stopped completely. I never could get it to work after that. The site's still there, too.
