Unable to open PDF documents

[Michelle Sor.]

I am suddently unable to open PDF documents after I have saved them using Windows 10.

I have uninstalled and re-installed Acrobat Reader DC several times to no avail.  I can save MS Word to PDF, open a PDF attachment from an email in my browser (Chrome) but once I save it to my laptop it cannot be opened.

Help please!!!

Michelle.

Any error message?

No error message. When I double click, it just isn't opening.
