I've had EN 6.25.1.9091 for so many years now I can't recall the last upgrade. I simply don't need or wish to access my notes on other devices and don't want private notes synched to a cloud. There seems to be no option to license the software on my own Win10 PC, so why why would I want to upgrade? This works fine as is, despite the incessant prompting to update. What I wonder is, what will eventually happen--Will it stop working at some point without an update?
