Hi, I am having a problem trying to open a PDF file. Ever time I attempt to open, Adobe Reader loads, but displays a rather cryptic error message: There was an error opening this document. Access denied. It's not a case of permissions, as I have administrative permission and can open all other PDFs on the server. I cannot copy it or move it. All of this suggests to me that the file has become corrupted. Can anyone suggest a way of pdf recovery this file without paying an outside vendor or using licensed software?
