I created a PDF file of high resolution. Then opened it in Acrobat Pro XI to compress the file for email. Now when I open a compressed file, it throws an error message"Error exists on this page. Acrobat cannot display page correctly. Please contact the person who created the PDF document to correct the problem I don't know what to do now, promised this file to one person in the near future(( Can as that to solve my problem with compression and restore pdf ? Thank you in advance!
