Old issue, no solutions found. User since 2006. New version 2.42 to 4.11 did a firmware upgrade to #121 without my consent, or i would have refused it. Now MVII license is lost. Unit will not log. And I despise windows10. Highly customized 2.42 is all I every needed. Don't lecture on the improvements, unless you can contribute a way to reload the older firmware 116? 118?. No solutions found on HPT or Google. I can restore my own license, not looking for a freebee. Help please to anyone who knows. Seen this so often it should be a sticky.
