Why, when MEGA is one of, if not the, most reliable filesharing services available? If you install the desktop app and use that to download from MEGA, the download is guaranteed to finish. You will still need to wait to get a new transfer quota, but you won't have to watch the time to be sure to resume the download exactly when the waiting period is up, because the desktop app does that for you, ensuring the file WILL be downloaded on the first try. And you don't have to pay anything for it. All you have to do, is install the desktop app and create a FREE account.
I never have any problems downloading any file from MEGA on the first try because I use the desktop app with a FREE account, while every other filesharing service I have tried, I have to restart the download at least once from the beginning, usually three or four times, meaning I waste a lot of bandwidth, not only for me, but also the filesharing service. Some filesharing services even deny access to their public files if they are too popular, which I have never experienced with MEGA.
