The FDM can resume the progressive download because the server where the torrent is hosted sends incorrect data due to unknown reasons. Therefore, your client does not understand what to resume and from where. Please clear the DNS cache by opening a command prompt (Start > Run> Cmd and press enter) and type: ipconfig /flushdns, then download the torrent again and see what happens. Stop it when the percentage is at about 5-10 % and resume it again.
