Well, can you use IRC? if you can, AnimeOne (#animeone@irc.rizon.net) has an XDCC bot with all the episodes of Tenjou Tenge on it. You can find the list here. Hope I could help.

P.S: If you don't want to use IRC, then you can get Tenjou Tenge from either here or here. Those places should work. Just use Azureus to download that one episode. If you don't know how, post again and I'll show you.
