The thing is in the outdated updates and TLS change. Here is in more details:
As a part of our continuous efforts to improve the quality and security of our services and to ensure our products meet the latest security standards, we have upgraded to the newer version of the security protocol (TLS 1.2).
On the March 31, 2020 Microsoft announced that TLS 1.0 and 1.1 will be disabled in 2020:
Online services and hosting companies update their security standards accordingly, so the TLS version on our server was updated to 1.2.
These versions of protocols (1.0 and 1.1) were used in Store Manager until December 2019 when we have implemented TLS 1.2. Store Manager versions prior to December 2019 will bring up “Unregistered Version” notification due to the outdated version of security protocol. If users have not updated as it was recommended in the release notes back in December 2019, they need to update now.
According to our License agreement, "Support, including technical support, is provided only for customers with active update and support period"... “Versions released 6 month ago and earlier are offered as is: https://emagicone.com/license-agreement/
We strongly recommend to update to the latest version of Store Manager and would like to offer you an extra 3 months of updates for free, if you order any of the Update Service plans on our official website:
