We apologize for the inconvenience caused, as per the description above, PDF files are not visible when you open it with Adobe Reader, Is that correct?
Open few files with Adobe Reader, go to Window>Cascade>Tile and see if this brings up any PDF file.
You may also uncheck these two options under Edit>Preferences>General:
- Uncheck Show online Storage when opening files.

Reboot the machine and launch Adobe Reader and try to open PDF files.
Please check for any pending updates of Adobe Reader from Help>Check for updates. Reboot the machine after the installation of updates.
