Windows updates like Portilis describes should no longer require a license reassignment - this was something we fixed several months ago, so it should no longer affect users.
Based on your support ticket, it looks like you updated to a new version of the OS (Windows 10 Home -> Windows 10 Pro). This changes some critical information about the computer, so to Hero Lab it looks like a new device - there's not unfortunately not much we can do about this.
I've flagged your license for an early reassignment and responded to your support ticket, so you should be good to go on this.
