text: Maybe you need the latest version.  PDF files designed for Acrobat 7.0 will not work in 6.0\n\nWhat I would do is uninstall all versions of Acrobat Reader you have, go to the adobe website and download the latest version of the Free Reader (Current version as of writing this is 7.07) and install it and try it again.\n\nIf that doesn't work, it would seem there might be another program interfering.
