Message "Object reference not set to an instance of the object" after opening Word file for final check.

Hi, I was just doing a last check of a translation in Word and wanted to insert the corrections straight away in Trados as I am delivering a return package, but suddenly I get the message "Object reference not set to an instance of the object". I wonder if it has anything to do with opening the Word file as I've been working on the sdlxliff file in Trados for days without any problems.

Any quick help would be much appreciated as I am having to deliver in an hour.

 

The error stack is:
