ERROR The requested operation requires elevation. Help please?

Sounds to me as if you've either uncovered a bug or contracted some
virus,
          therefore, I would suggest:

       (1) if a bug, then revert back to a previous version before this
occured;

       (2) if a virus, then run the various A-V programs until your system
is again clean.

       Meanwhile, go behind-the-scenes to the LO file-folder;
          gather all your data;
         save this elsewhere for safe keeping.

       Hoping this helps,
