Hi Ashraf,
First of all, sir, thank you for obtaining license keys for Sticky Password Premium. I do, however, believe that you MAY have your license keys mixed up.
I’m an existing user, but when I attempt to insert the license key offered for Existing Users, I’m greeted with “The License Key you entered is expired or invalid.” If, however, I use the license key for New Account it DOES successfully increase the length of time that my license lasts for.
Fixed, thank you. Sorry about that!
