here's a simple existence check
open the EPS, it's human readable. you'll see if it's capable of drawing and arrow by reading it
unfortunately at the top there will be many "wolfram function definitions" (in the postcript language) that setup fonts and such in the PS language. (you skip past that looking for the arrow drawing part of the file which should be at the end). these are not as correct as they were in previous versions (i think wolfram has slacked on it, thinking 3d is everything and 2d is nothing)
you could just post the .EPS here on this website, and someone else can try loading the file and tell you what they see.
MY ADVICE IS: make sure you have "Adobe Reader" installed: you need Wolfram fonts and likely adobe fonts installed in windows 10 for EPS files to view properly. Also: try viewing the first in Adobe reader before you try "Word 2013". unfortunately your using and OLD version of a microsoft product, so it may not be able to use the fonts and won't be supported by anyone for such a problem. the microsoft team (at wolfram and microsoft) are not the same as the Apple imac team. they may have changed fonts in some way.
also: you can read the EPS in mathematica by pressing (shift-apple-e, on apple) by using "show cell contents" after you've loaded the EPS in mathematica
