We are a small group of teachers that produce monthly current events teaching units for Canadian schools.
Some of our our customers receive the newsletter by mail, and the rest download pdf files from our website. The pdf files are password protected and we notify our subscribers by email what the password is.
We have never had never experienced any major issues, until now. We recently upgraded to Acrobat Pro version 9 (from 8) and many, many subscribers have been contacting us claiming that they cant open the password protected files even though they are using Adobe Reader 9. When I create the pdf file, the settting I use is open with Reader 5 and above.
Many of our customers are very frustrated and so are we. Can anyone please help ???? Is anyone else experiencing problems and what can we do to solve this?
Adobe Reader 9 opens the password protected file OK.
Preview says the file format is not recognized and/or the file is corrupted (when it is not).
Many other customers are reporting other problems -- grey screens, no password being asked for, etc. etc. (but when we email them the master pdf file without a password, they can open it OK.) Somehow the security settings created by Acrobat 9 are causing the problems.
