This is the best way of operating. Sadly, it seems most people are terribly careless
about such things. For them, there is always this:
https://groups.google.com/g/video-downloadhelper-q-and-a/c/BzPLK2YyL-s
Search for "lost" within the text of that web page. You'll find instructions there for
how to retrieve your license number if you have been careless about keeping the important
document that is the E-mail sent from VDH confirming your purchase of a license. That
E-mail also contains a link to your invoice. If you lose your invoice, there is no way
to recover it, like there is for the license. You should download your invoice to your
computer & save it as well.
If you have changed ISPs & the E-mail address you used to purchase your VDH license no
longer exists, you have to send an E-mail to Jérôme at
jcv...@gmail.com (jcvdh56 @
gmail.com) asking for his help. Tell him your old E-mail address & your new one. If you
can come up with further details, like when you bought the license & for which platform
(Windows/Mac/Linux, Firefox/Chrome/Edge), that can also be helpful. It seems that if you
have more than one license, like say for both Firefox & Chrome, the self-help license
retrieval gives you only the Firefox license. In this case, you are forced to E-mail
Jérôme for the other license.
So yes, keep important documents. Just because they are mere E-mails doesn't mean you
can just mindlessly delete them. Save them some place where you can find them again
later. You keep important things like your driver's license, your car registration, the
title to your home, tax documents, wills, other physical objects of importance in a safe
place. Treat these E-mails the same way.
Then there's the weird issue of the disappearance of the Google Pay support for Chrome
licenses. Back in the days when Google Pay was the mechanism for buying a VDH license
for Chrome, users didn't get a formal license number. They just logged in on Chrome &
poof, their VDH registration was in force. But when Google Pay yanked the rug out from
under VDH, Michel reacted by changing the management of the Chrome licenses to the same
way as has always been done for Firefox & Edge licenses. Chrome now needs an explicit
license, same as the other 2 browsers. But people affected by Google's abrupt action
don't have a way of doing the self-service license retrieval. Their only recourse is to
E-mail Jérôme & get him to send you a license number. I find it weird that this is still
an issue. I mean, the Google Pay thing was stopped about 2 years ago, if memory serves.
I don't understand how people can still at this late date be getting caught out by this
issue. Whatever. That appears to be the case. Instead of complaining, as they've been
doing in here for the past few weeks, they should just E-mail Jérôme & he'll take care of
things.
