Assist with having the ability to play area pioneer

I just lately re-downloaded a cellular recreation known as area pioneer, however because it wasn't obtainable on the play retailer anymore, I obtained it by means of an exterior web site. Nonetheless, every time I attempt to play, as a result of it's ready to hook up with my Google play account (which is sweet for me) it nonetheless gained't let me play, saying "the app put in in your system just isn’t acknowledged, and will hurt your system" however the issue is, when it says "strive trying to find it on the play retailer" as you’ll be able to 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’s threat. Is there something I can do as a way to play the sport once more?
