@Ronn62353 Have you tried swearing at it?
Seriously though, it's possible that the .torrent file got screwed up when you downloaded it. It's rare, but sometimes I'll download the .torrent file and get told the download was cancelled due to failing a virus check. If I try again it works fine. So I'd say, delete it from your client, maybe do a reboot and restart the client, then download the .torrent file again. Might not work, but worth a try.
