Adobe Acrobat
I purchased Adobe Acrobat in order to convert Excel workbook (multi-worksheet) in to ONE PDF document.
This has resulted in my inability to even see my previous documents in Adobe Reader. My MAC now says my
Adobe Reader.app cannot be opened. It is followed with a code of 1712.
Furthermore, when I tried to send my own PDF from the cloud to my own email address, the system says that
I cannot open because it is from an "unidentified developer".
