The links to the zipped files don't work very well because you will often get disconnected from the hosting server before the file completes, which is what happened in your case. These files are very large and even on an extremely fast internet connection should take at least 30 minutes and probably closer to 1-2.5 hours. I recommend using the torrent links. Send me a PM if you aren't familiar with torrents and I'll explain everything to get you set up.
