Can't publish to .pdf Solution

While using Corel X3 I ran into the same problem.  Publish to .pdf quit working.  Went thru all kinds of "cures" in suggestions. Finally, I pushed Publish to PDF one last time and I noticed the "settings" and noticed that the default selection was "selection "  in the drop down choices.  I selected "pages" (showing all 6 pages) and it produced a good .PDF. Just click OK and then "SAVE".  iT ALSO SEEMS TO WORK WHEN YOU SELECT "DOCUMENT".  HOPE THIS WORKS FOR ALL!
