Unable to open all pdf documents

[merrilli71462603]

Hi All,  please help.  Since yesterday I keep getting this error message when trying to open all of my pdf documents.  

This is a document I could open before and it definitely is a normal document that opened fine last time.  

I have reinstalled Acrobat Reader and have done the updates - please help?

Question moved to Acrobat Reader forum.

What can you see when you open the file in Notepad?

Acrobat Reader can't open empty files.

The file isn't empty, it's 340 kb's.  Notepad shows empty though

Not looking good. Take a look in Windows File Explorer at the file sizes. Are they all zero now? If so, there is nothing there.

Are these old PDF files from before, that used to be OK --AND-- you saved and kept them on your computer? Or are they coming down from the internet?
