Hello I have scanned one of my magazines and changed the jpeg to pdf using Adobe Acrobat 8 Professional. I have transferred it to my ipad using itunes and it sits in my ibooks section. However, I can't open it. I select it and nothing happens. When I used Adobe Acrobat 8 Professional, I converted the jpegs to a binder. Could this be the problem? The total file is 122 pages long. Any help would be appreciated.
