Thank you Edna, you were right in assuming I had used incorrect terminology, I should have said "not loading on boot-up" & not that it was un-installing on boot-up.  All I noticed was that it did not appear in the Messenger Programmes.
I had overlooked "Force Messenger Plus! to load when computer starts" in the Preferences>General Options.

All is well now...............once again, thank you for your prompt assistance.
