The listings textbox does not accept formatted text.
So (for example, there are more options, depending on WORD version) you first need to save the Word document as plain tekst file (.txt) and then do the copy/paste from that one.
Or open Notepad (or other plain tekst editor), and paste text first in there, then copy text again from editor screen.
Also the listings textbox has limited amount of characters, do not exceed.
