I am running into a problem with an increasing number of things I attempt to read on line. I get a message telling me the item cannot be read, usually a PDF file, with my current version of Acrobat. When I looked up Adobe Acrobat hoping to find a free update or at least an inexpensive one I find that the price of Version 9 is hundreds of dollars! Is anyone else having this problem? I did come across a number of offers for a free download of Version 9 but I won't take a chance because I've been warned that these free software offers are often invitations to download malicious viruses.
