Q. I'm trying to save this document in Word, but it won't let me.
Sometimes, when you edit a document using a different version of Word, Word will not let you save the edits in the .docx file type. The solution is to rename the file and save it as .doc file. Be aware that some features available in Word 2013 are not compatible with the older .doc file type. You will need to go through your document and check all of your citations, references, and formatting.
