Typed pages become blank...

I use a PC.  I recently installed Windows 10.  I have Acrobat Pro XI.  About a month after Windows 10 installation, when I opened PDF documentsI could read all pages.  But, after some time viewing different pages, I would go forward or back in a document and find a blank page.  Other than length of time open, there does not appear to be a reason the page goes blank.  When I close the document and re-open it the blank pages come back with any notes, tickmarks, etc. included.  Does anyone have this same issue and was it resolved?
