It will be working soon (in a couple weeks?). At least that is what Snipes told me. (evilones.net) Just wait it out or try the torrent.
Well, since I had scratches on my old CDs that made them useless, I tried the torrent from Freespacezone.com.
Even though this is a very old thread, let me mention that CD2 in this torrent has a wrong filesystem and neither can be mounted nor burned. The other stuff works fine, it's just CD2.

It's also curious, that it's called FREESPACE2_DISC2.ISO while the other ones are called
Freespace_2_(1999).CD(1 or 3).ChAoScReW.ShareReactor.ISO.

With this exception, the torrent has more than 10 seeders and is fast enough (26hours for 2.4GB?).
