First of all, I would like to say that you downloaded your file directly from our paid servers in google cloud. Google's explanation for downloads stuck at 500Mb: “if there are too many tabs open on the computer and the computer is used intensively during the download process, such a situation will occur.” You can try clearing your browser cache, disabling security applications in your browser or whitelisting our website. Also make sure you have enough storage space on your computer to download the file. Can you try again with this explanation in mind please.
