Dear magdyharby1 and others,

I found the problem and solved it, you need to installed the new edition of Adobe Reader,
My laptop installed ver. 7 can't read, but Today when I put the file into my desktop PC, using ver. 8.1 also can't,
but I can open it using other PDF reader and ver. 9.1, so I download the latest version form Adobe site, is Reader X ver. 10.1,
right now the file can be open and no any problem. I though it is the PDF reader problem.
And thank magdyharby1 to reload again!
