Hi,
I bought a Macbook Pro (OS X) last week and installed it with the trial version of AutoCAD LT 2015. It ran smoothly and without a hitch until yesterday. I printed a plan to PDF but when I tried to open the PDF file, an error message kept popping up that says "There was an error opening this document. The file is damaged and could not be repaired." Even if AutoCAD says "Plot and publish job complete, no errors or warnings found," the error message appears on both Preview and Adobe Reader, and even Safari, when I try to open the PDF files I printed.
I was able to print PDF files successfully last week, though. Any advice would be greatly appreciated.
