Hi Holly,
I split your reply off and turned it into a question because it does not seem related to the topic you replied to.
What version of Word do you run? Use the Menu Bar and choose Word > About Microsoft Word to display the version information and license type. What does that dialog tell you?
Did something change today on your Mac? Install an update or add-in?
What steps are you taking to save your files? Exactly what is the error message (if any)?
Did you try simply restarting your Mac?
