Some users said this is a problem with the browsers, but it has been reported that even the change of browser still displays the same error. In the final, the actual problem is related to the TORRENT file itself. The server that's issuing the torrent files isn't working just fine and because of that the files are corrupted. Try to download the torrent files from another source. It has been reported that the change of torrent source, overcomes this error and the download starts (if there are enough peers). If you keep receiving the same error after all these, switch to uTorrent instead.
