since some update from Reader 8.1 to 8.1.2 I cannot print PDF files anymore. Meanwhile I installed Reader 9, but with no luck.If I crank up the preferences I get the error "Failed to load an application resource (internal error)." ... maybe there is something wrong with the installation, but even an reinstall doesnt fix it.If I try to print I get only the message "The document could not be printed" and then "There were no pages selected to print." ... no matter what PDF I try to print.The Apple Preview works without any problems, so the PDFs should be good.Can anyone help me on this ... its really frustrating.Best Regards--Michael
