    The document cannot be opened because it is not a valid PDF document


      I've just installed the latest mobile Adobe Acrobat for Android. I was able to open the first document I tried, but since, the other 5 documents on the same website render the above statement, and, of course, they don't open. Any suggestions? I know these documents are indeed valid PDF documents. Thanks!
