PDF showing only 3 pages

Hi,

I have exported a webi document with three reports to PDF. The total page count for all the three reports put together is around 500. In the PDF i am seeing only pages 1-3, though on scrolling down i can see the whole of document. The issue here is when i try to print, i can select only pages between 1 and 3.

Any idea why it is showing only 3 pages and not 500? How can i get all the 500 pages to be displayed for printing?

Thanks,
Arun
