1. I used the QTM and filled everything and selected the single file.
Good
2. It uploads to the site (the torrent is there, dead) and nothing happens.
Yes.
3 I read that after the upload, QTM sends the task automatically to uTorrent, but it didn't happen here, my uTorrent showed nothing.
Hmm…
When the torrent has been uploaded successfully, and the auto re-download + launch on uTorrent didn't happen, you can try:
manually downloading this torrent file onto your computer (click the download on the torrent page), open it in uTorrent, locate the files on your computer meant for the share, force re-check, make sure it goes to 100%, and START the torrent.
