You are wonderful to take the time to give me advice! Thank you, Leo. You do not work for Microsoft, do you? I wish you lived near me so I could pay you to fix the problem. I am reluctant to remove Office in case afterward I am not recognized as having a Microsoft account even though I pay a fee every month. I think I will try to reinstall keeping my fingers crossed hoping my new account will be acknowledged.
Thank you for all your support.
Have fun!
