Helo Dorothy and thank you for choosing JustAnswer.com
My name is ***** ***** will be the expert helping you today.
I am reviewing your question and will reply back shortly.
The best way to help you in s situation like this, would be to connect to your computer to SEE the error in action, and potentially fix the issue.
The fact you have lost access to your MS Word is very suspect, and reveals a bit as to the nature of this problem.....possibly a virus or trojan or malware.
I would start with doing a clean up of your system, and scan for nefarious issues.
YOu may have Anti-Vuris, and you may not......but either way, you can STILL get virus's......it happens.
So please let me know when you are ready for the Remote Session.
