I have just come to the end of a translation of a very large Word document in Trados Studio 2017 and am unable to open the translated file. The error message says:

"We're sorry. We can't open [file name] because we found a problem with its contents". 

When I click on 'Details' it says:

"The name in the end tag of the element must match the element type in the start tag"

What does that mean?! I have read similar queries on here where the suggested solution is to remove the table of contents as a possible way around this.  The ToC in this document is huge and if this is really the only way around this it is going to create a huge amount of work for me (this comment aimed at SDL!) Presumably once you've done that you then have to manually re-type it - can that really be correct? The document itself is full of tags and formatting in addition to the ToC.

Any help gratefully received.
