Who created that document and how?
What is your Reader version and platform?
do you say I should refer this problem from the author? I try to open another pdf from the same author, but all texts go missing on the tables and figures as well. By the way, I'm using version 9 and did update the reader already. Not sure what else is missing.
It is difficult to determine where the problem lays; I would first try to view it on a different machine - perhaps with a different version of Adobe Reader.
If it shows the same way, I would definitely contact the author.
