I keep getting this error message whenever I try to open any new PDFs

"There was a problem opening this document.There was a problem reading this document (11)"

I have checked the security settings, redownloaded Adobe Reader DC, uninstalled, reinstalled, and converted old files to PDF.  I cannot open anything new.  Even documents saved as PDFs from the Adobe website will not open. 

I need to be able to open and download PDFs for my job, anyone able to lend any suggestions?Acrobat Reader​Acrobat​Standards & Accessibility (tagged PDF)​

So I have figured out the issue.  The file I was using had an unverified signature.  It caused the file to be corrupt and shut down my Adobe Acrobat Reader and locked me from opening any other documents.  If I closed the document and restarted the program it would allow me to open other documents.  In conclusion, I redownloaded the document without the signature embedded in it, resigned it and it solved the problem. 

Hope anyone who has the same problem can use this information to solve their own.
