Sorry if I'm being stupid or stating the obvious but AFTER you download your own torrent you should open it as usual in your torrent client and then point your client to the exact file you made your torrent from.
You are not trying to 'download' -if your torrent client says it is 'downloading' your file you haven't pointed it to the file on your disk.
Again apologies if I have stepped on anyone's toes or am teaching granny to suck eggs 🙂
