Word 2010 - Error with page numbering.

[amk48823]

So I have page numbering in the header of my page. I have content on the front and back of each page. I have ten total pages in document. In word, the front page (of sheet 1) says 1 of 10 pages, the back side says 2 of 10 pages, the front of the next page says 3 of 10 pages and so on.
But!! When I print the pages, the front page (of sheet 1) says 1 of 1 pages, the back side says 2 of 2 pages, the front of the next page says 3 of 3 pages and so on.....why is this.
When someone else on a different computer opens this document, everything prints perfect.
Can anyone help?



Thanks
