It appears that your new license version is mixing with remnants of the old one causing that popup. It shouldn't happen but sometimes it does unfortunately.
Uninstall all McAfee software using Control Panel > Programs
Download and run the MCPR cleanup tool listed under Useful Links at the top of this page or HERE.
Reboot and then reinstall from your online account.
Although I don't work for them I apologize on behalf of McAfee for the inconvenience.
Let's hope so. ;-)
