Thanks, when I log into my account with them, I can review my purchases and at the bottom of each product purchased it shows a date when that file was last updated.
As I've said, if they followed our instructions, what they have sent you is NOT the actual installer, but just a link to our site to download it. The link itself NEVER changes so, whatever date you see, it's entirely irrelevant with our products, because they couldn't possibly know if the file linked has been updated or not.
But that's precisely the point: you don't have to wonder about file dates. Just know that, whenever you click on that link, is ALWAYS the very latest version available.
Since the installer is always freely available on our site, it takes less time to just download it anyway whenever you need to reinstall it, and don't even worry about keeping a backup of it.
The issue is, most retailers websites are made around the concept of "download after you pay", they are not really suited to the "download before you pay" we use, so it might get a bit confusing sometimes.
