Same issue with my phone. Problem seems to occur with any prompt or manipulation of document. Example swipe screen to turn page pops an error code, expand or reduce text or image pops error messages. Any command or browsing execution in PDF initiates an error message. This device is 8.1 with a build date of Nov 2014. Newer device on 10 with build date of Jun 2016 no issues with PDF is it hdwe specific or OS specific?
I also have Windows on a Nokia Lumia and encounter repeated, ( nearly 15 times !) error messages when I open any PDF.
my version was downloaded from the Microsoft store as well.
Is there a fix yet??
I wonder if the Windows platform has gone the same route as the 8-track.

I just upgraded my Nokia Lumia to Windows 10. I have the same issues as described above but I also have not been able to install ANY new apps. I get an error message after going through the download. I have been trying to edit this for about 10 minutes. I couldn't get the cursor to return. It was stuck at the top of the page. Anyway, thanx for listening and, hopefully, figuring out the fix-it. Sincerely, Judy Soodyshoe Simmons-Morris
