When I click on a question mark I get an error message. Whats wrong?
You probably don’t have a recent version of Adobe® Reader® installed on your computer. To view the PDF files that open when you click on a question mark, you need to have Adobe® Reader® version 3.0 or higher installed. Adobe® Reader® version 5.0 is included on Phytopia, so you can install it from the CD, or you can install the latest version of the free software from the Adobe® website.
