PDFOffice Addin keeps disabling

I have Adobe Acrobat DC installed. I convert a lot of word documents to pdf however the Addin keeps getting disabled.

it's location is: C:\Program Files (x86)\Adobe\Acrobat DC\PDFMaker\Office\PDFOfficeAddin.dll

I re enable it and as soon as I try to convert my document I get an error message that 'word has stopped working' and then a new blank word document appears with the Addin disabled again.

This has only started to happen recently....I have automatic updates for both MS Office and Adobe.

I am running Windows 10 Pro - 64-bit and MS Word 2013

Does anyone know what I can do please
