I'm pulling my hair out. Yesterday, I was able to create bookmarks. Today, I'm getting an internal error. I can't create any bookmarks, and eventually I get the error message (attached). I've tried repairing, rebooting, checking for updates, etc.
When I'm looking at the document, I can see the panel with the page thumbnails (attached). When I click on the icon for bookmarks, there is no title or heading, and no bookmarks either (attached).
I scanned it via ScanSnap. At some point, I did an OCR scan. The odd thing is that I have about 10 similar files. Only the first one or two have been OCR scanned. The bookmark issue happens on every file I open.
Can you creat bookmarks with a PDF made from another tool? I'd sugges you try workng wih a PDF that did not come from ScanSnap to see if it's the naure of the PDF that is having problems with bookmarks raher than Acrobat.
