Remove the torrent download it again and then force recheck then force start the torrent if it still not working try to update tracker if not so i am sorry i don't know what to say just as Viktor or any other profession

simply download the .torrent file again. if it doesn't work, then try to erase your browser cache, and try downloading again. if the .torrent file itself would be incorrect, then there would be absolutely no seeders/leechers on it, that way it wouldn't show up on torrents page.
