Blacks not displaying in Acrobat Pro

When I view a PDF in Acrobat Pro, the blacks are suddenly appearing as grey, or even not displaying at all. Any ideas why?

• Can you specify the exact version of your operating system and software
• Is this a new issue or something hapening after an update or upgrade 
• Is it hapening only on certain files or any PDF you open
