PDFCreator printer error

I've used this program for years without any problem but for some reason I keep getting an error message when I am trying to create a PDF.  I am trying to convert a Word document, which has always been easy.  I just keep getting "Error - Printing" under the "Status" column in the PDF Printer window.

I tried unistalling and installing but it hasn't helped.  Any ideas?  (I should note that I am not very skilled with things of this nature so please be kind in replies.)
