[Watermark]

I am unable to remove a watermark on a Word 2007 document. I had saved it as
a 2003 document with the watermark so that colleagues who did not have word
2007 could read it. Later i made more changes to the document saved as a
2003 document and saved it as a 2007 document again (overwriting the original
2007 document). Now I am unable to remove the watermark from the word 2007
document. Help!
