My download crashed several times and I always gave up, so I tried to change my browser and wait, amazingly I managed to download piry in less than 3 hours. It used to take hours and hours to download a file.
It may have been a coincidence. I downloaded it on a Saturday, the other times it was on a Wednesday and a Thursday.
It may have been the day or maybe the browser I used to download piry, I don't know, but I just say one thing, wait an hour for the download to finish.
Try another day or another browser. It worked for me.
