I have received a PDF file as an attachment to an email and can open and view and print it from within the email but when I save the file to my computer and then try to open the file I get an error message saying that CIDFont+F1 cannot be created or found. The file opens but the text is just displayed as a series of dots.
I have confirmed that I am using the most current version of Adobe Reader.
Any advice on what the problem might be and how to resolve would be appreciated.
