X8.1 does not work anymore with Word 2016 (16.9) for Mac.

Thank you Jason. I’ve tried those instructions. I rolled back the Word using that link but when I reopened word it came up with an error message saying _The Microsoft Office Document Cache encountered a problem _and word needs to be restarted. I close word and reboot the macbook pro and it doesn’t clear so I can open the roll back version of Word. Can anyone help? Many thanks.
