It sounds like your problem is a combination of two things. The first is that there do not appear to be very many leechers actively downloading any of the torrents that you have in your profile. If you were to start seeding torrents, I can see what I can do to correct that part of the problem.
The other part of the problem has to do with your port forwarding. I would be very surprised if you have correctly setup the port forwarding in your network. See, you need to make sure that the port that your torrent client uses is forwarded in your router to your computer, both in TCP and in UDP. Without this, getting any kind of upload traffic with our tracker can be very difficult.
