Resetting glasswire basic serial number

upgraded to glasswire basic back in may 2015…had installed it on windows 7 x64

just upgraded to windows 10 pro on same PC, had to re-install everything…still have my original email…with serial number{backed up emails before the OS upgrade) …but glasswire says serial number has been used too many times (WTH?)…any chance my serial number can be reset…or even a new serial number? not worth paying $58.80 again…for another upgrade…

I already have glasswire free installed…

Please forward me your order email to our contact email address here https://www.glasswire.com/contact/. I’m glad to send you a new activation code or make changes to yours.

there are 3 different email addresses i see…which one do i use? help@glasswire.com, bugs@glasswire.com or, business@glasswire.com?
