Hi !
I've just got the issue. Using Chrome, when I click on "Download", nothing is happening.
After checking browser's console, the issue is the download link point toward an HTTP address. While this site use HTTPS. For security reason, Chrome block the link.
If you have this problem, right click on the download button and "Copy the address". Then past it in another tab and add the "S" at HTTP. Your download should starts correcly.
