I tried all the steps indicated in your first two links. No luck. Today when I try to open the pdf file it opens normally (fully able to read the copy at normal density for about 1 second), then the type immediately becomes faint and broken up and unreadable again. Maybe slightly better than yesterday. Thank you for your help. I haven't had any luck with the Adobe support yet either.
