SunLei 7 download problem

supernova

I had installed the Sunlei 7 long time ago, In the past few weeks, when I clicked on the torrent links to do the the download, the download sites stated that "The (movie) download is intended for SunLei 7 only and I need to download the Sunlei 7 first". The site showed me the torrent for an .exe file  but never the torrent for the movie. What have I done wrong. Are the download sites playing tricks on me? Please advise. Thanks in advance for the help.
