I also have Win 7 / Word 2010 and just gave it a try.
I got the "cannot initialize" message in tracked it down to this piece if text.
If I delete either the last bracket or the full-stop then it is fine.
So it seems to be a combination of characters that stops it.
If I press "Replace" the full-stop is deleted.
