Last Friday, when I just wanted to save a *.docx document at the end of the day, I got the system message ...
ERROR: A file error has occurred...
... resulting in no word file created (a file existed, but the size was 0 Kb). Well, Microsoft is funny - at the end of the error message they ask:
Is this information helpful?
What is the solution? I don't know for sure, but in my case the following actions did the magic:
- turn the track changes off
- accept all changes
Well at least I could save the document as *.doc without those actions above.
