I was unable to download until I opted to use the link with provided download
manager. I did not want to install anything else extra, but at least I'm able
to download. Granted, late last night, the download stopped a few times and
there are no options to have it automatically restart it for you, so when I
went to bed and woke up, I found not much more had been done. Oh well, this
morning, it seems to be moving at a much nicer speed. Are you trying that
link or the link for you to download with your own download manager?
