Assist with with the ability to play area pioneer

I not too long ago re-downloaded a cell sport known as area pioneer, however because it wasn't accessible on the play retailer anymore, I acquired it by an exterior web site. Nevertheless, at any time when I attempt to play, as a result of it's in a position to connect with my Google play account (which is nice for me) it nonetheless received't let me play, saying "the app put in in your gadget shouldn’t be acknowledged, and will hurt your gadget" however the issue is, when it says "strive looking for it on the play retailer" as you may see close to the top of the video, it's not there, and it doesn't present an possibility for me to play the sport regardless, even when there may be danger. Is there something I can do with the intention to play the sport once more?
