My film wont play?

well - i downloaded paranormal activity. & it says its on divz. but its not. when i click to play it, it says 'you need playvix to watch this film'.
but i know playvix is a scam so how do i watch my film?

I can't help you with pirated videos but if you were to have downloaded an .avi or .mkv file off a torrent site and when played with something like VLC and it shows that, your video is empty. It's likely that was intended to be some sort of scam and your best bet is to find another source and download it again.

Again, video pirating is illegal and this is solely for personal video usage. =)
