OK, if you got the tracker error, try this. Although when you register for filesoup you can immediately get into the forums, you will still get an email that instructs you to activate your account. Do that--after I activated the accound my torrent download worked.

Also, good news: my previous download from the suprnova.org torrent seems to be the one now on filesoup, so that's 30% already done and more bits to add to the torrent pool. My upload is at maximum so somebody out there is benefiting.
