Hello Lyne. 

I am not sure how this is happening for you. I just went in and logged in as you to your account. I went to your most recent order which is 112472121 and I downloaded all of the products in that order by using the productname.zip links. Not the S3 links. I have made a screenshot  of  my downloads folder for you with the times they downloaded so that you can see they download with the file names as they should for me. If you would send your browser name and version number to us at store@renderosity.com with a screenshot of the files you downloaded so that I can show it to the programmers please? Thank you.
