I currently have CCleaner Professional & kept getting notified Kamo was not working because I already had a VPN installed. I finally figured that out & uninstalled that old app. It instructed me to uninstall & reinstall Kamo. I installed a trial version because I didn't know another way to do it. How do I get Kamo back as part of my paid subscription?
You need to re-enter your code to activate your subscription, Menu>Settings>Activate enter your code as asked.
