Object null reference error while loading a docx file from stream

[K]

I can download and open my docx file but can't preview it from browser. I can't find what's wrong. Any help would be much appreciated.

I attached my docx file

Here is where I get the error:

WordDocument doc = WordDocument.Load(stream, FormatType.Docx);

And here is the stack trace:
