I have a similar problem that Larry Joy asked about on this forum. Per my usual practice, I updated my Adobe Reader to 11.0 when it was noted by my softeware update app. Since then, I find that .pdf documents dating prior to the update have black boxes over all text, tables, images-essentially all content except the file name, date and title. Many are saved emails that I save via the <Command P> then <Save as PDF> procedure. My printer is a Canon MX879 aio, with a current driver. My iMac info is a 2.5 GHz Intel Core i5 processor, using Mountain Lion OS 10.8.2.
Most of these blacked-out documents were created using Adobe Reader 9.5 and Lion and Snow Tiger OS versions.
Can these documents be reconstructed? Much of them are critical and irreplaceable (though backed up) if even the backed up copies cannot be read.
How should I proceed?
