I just tested the download, and I get a pro.zip file. @PYS
What the dev is saying is are you positive that as you are viewing / exploring the files / folders structure on your machine, it is not treating the .zip as a folder?
On Windows (Explorer), while viewing folders and files, windows can be set to show the files within a .zip making it appear to have been unzipped, when infact you are ‘exploring’ the actual zip file itself.
If on windows use (explorer) or MAC use (finder)… start a search at the root of the drive that you downloaded what you think is the pro folder (which should be pro.zip)… and do a search for exactly “pro.zip”.
What do you get in search results, do you see “pro.zip”?
