I am having the the same exact problem. I have installed WD Photos on my Samsung Galaxy Tab 10.1 running 3.1 and my Galaxy Nexus running 4.0.2. I set in the activation code into both, but it says that there are no photos to view, from my hard drive (the ones avaiable synced from my mobile device gallery). I have not been having any issues with WD 2Go, my files appear on that, but I am getting nothing from WD Photos.
My files are jpegs, but are still not showing up.
Any advice?
