how did you come to the number of 100 people having downloaded it? I think it was showing that 100+ people were in the process of downloading (leeching) when you quit seeding.
torrents take a while before the are self sustaining. 10gb uploaded of a 4.5gb torrent is really not that much when you are the original uploader. to successfully upload a torrent, especially on a public tracker, you need to be willing to seed for quite a while.
the fact that you had 100+ people interested in you edit ahould be encouraging. most do not get near that ammount.
people are interested, and it would be a shame if all your hard work would go unshared.
