when you look at http://ctorrent.sourceforge.net/ they say
CTorrent discontinued -- 2006-06-07 15:46:51

While this is old news, I thought I'd put it up on the webpage as an official annoucement. The ctorrent project has been cancelled (finally!). Ever since the main developer, YuHong, left the project back in 2004 there has not been a single release.

ctorrent is dead and we need a new one then the next post on http://ctorrent.sourceforge.net/ say

Enhanced CTorrent -- 2006-06-27 03:23:40
I just stumbled across Enhanced CTorrent, which appears to be a branched version of CTorrent with numerous new features, improvements and bug fixes. It also incorporates many of the patches queued up here on the CTorrent Sourceforge page. I have not been able to reach the author, nor have I personally evaluated his work, but it looks really good! You might want to check it out as a better alternative.

and im thinking when i Main dev of ctorrent say that Enhanced CTorrent looks really good! then why not just delete ctorrent and get Enhanced CTorrent in :)
