I can't find a way to drop my Pro subscription and go back to using the free version. My license has expired and I can't justify the cost of continuing. The nagging is getting very annoying. Any help for that, other than wipe and re-install?
That's it - the renewal nags should stop in time, but otherwise uninstall your curent CCleaner and reinstall the free version.
You will still get the occasional nag to upgrade/purchase Pro.
