Einstein Riddle not running, why?

[groston]

I have played Einstein Riddle, by Rottz Games, for quite a while. Starting about two weeks ago, when I try to run it, I am presented with a screen that says “Get this app from Play – The apps installed on your device is not recognized and could harm your device. To continue using this app, search for in on Google Play.”

When I go to Google Play, the app cannot be found. Turns out that I had installed it from UpToDown app store. Additionally, my phone is rooted and I have disabled all automatic updates. What is going on and, more importantly, will I ever be able to use this app again?
