As far as I know, these torrents are available in Torrentsearch and Torrentreactor named as Pre SE LD rip.
Torrentreactor lets you know if a torrent is currently seeded and if the tracker is properly running, so you could check that. But as I can see, Torrentreactor is down at the moment (Is that a coincidense?). As far as the "ConnectException:Connextion refused" message, It seems to me that you have an instace of your torrent manager not properly shut down so you are refused a second connection by the tracker. In that case rebooting should fix the problem. Another explanation would be that you blocked several ports via a firewall, and the tracker does not allow firewalled users, but I think that is unlikely...
