Hello,
I am new and non experienced with this forum, sorry.

Background:
I purchased VideoRedo Version 4 software on December 10, 2012, to install on my desktop PC.
I purchased VideoRedo Upgrade to Version 5 on February 28, 2015, for the same PC.
I purchased version 6 on February 22, 2020, which I installed on my recent laptop, which still works fine.
Problem:
In the last few days, I reset my old desktop PC to properly reinstall Windows 10.
I had to re-enter my license key, but unfortunately, I mistakenly entered the key for version 4 (December 10, 2012). Since then, I've been stuck with the manual activation issue: see screenshot 1 attached.
Then, after downloading it, I installed the latest version 6 found on your VRD forum in another Windows folder, and entered the license key from February 22, 2020. I'm also stuck with the manual activation issue. See screenshot 2 attached.
Questions: Could you give me some advice on how to restart a version of VRD on my desktop PC?
Is it lost forever?
Unfortunatly I don't see any way to join screen copies.
May someone help me ?
Than you
