How did you create the torrent?

What torrent client are you using? (Client = app = qBittorrent or uTorrent, or Transmission, or similar.)

Did you download the .torrent file from the site and launch that one in your client, or are you trying to use one you created locally yourself? (That won't work.

Could you post a link to the torrent description page that was created? That may give a couple of clues.
