What OS did you use? If it was Windows, that might be the reason for your fault.
Earlier, when I used Internet Exproler for downloding, the process stopped short at 2GB of 4.7 with the wrong checksum.
After using Linux Mozilla Firefox download, I managed this from the very first attempt, although explorer download is considered less reliable for such large files.
