Here is a play by play of my downloading the file:

The image above shows my browser open, the file downloading and the folder where it is being downloaded to.  You can see that there is a zip.part indicating the file is not finished downloading.

If it was a problem in my method of downloading, I shouldn't be able to open up any of the other zip files I've downloaded.

The problem is exclusive to this one single file. None of the others that I have downloaded at the same or different times.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
