I wanted to search for a particular topic in all previous 36 issues of digit magzine. But when i double clicked on the file DigitArchive.pdx (June 2004 issue CD with name 36 archived issues of digit) a message box appeared and said that "Adobe Reader could not open 'DigitArchive.pdx' because it is either not a supported file type or because the file file has been corrupted(for example, it was sent as an email attachment and wasn't correctly decoded)". what is the problem? please help. I am using adobe reader 6.0 and internet explore 6 and windows 98 se.
