I highlighted almost 200 pages on my file these few days using Acrobat Reader, everything is fine (since I save the changes every time) until this afternoon, I tried to open the file but it failed to do so and the error stated was :" There was an error opening this document. The file is damaged and could not be repaired."
I tried to open other PDF files and it was fine, so the problem is only on that particular file.
I tried several solutions available online (such as repair the file using Stellar Phoenix Repair for PDF, but it just appeared that the status of my file after repairing is "junk file", and it is failed to preview, failed to be saved) but they still can't solve the problem.
So, I post my problem here, hoping that there are useful solutions for this problem as I do not want to highlight all 200 pages again.
Thank you.
