Keyboard disappeared

[Android Central Question]

The keyboard that I had downloaded,from,google play has disappeared. I unstalled the app and,reinstalled it and it just remains black at the bottom. U can see a little of,it at the edge of the screen but it's all,distorted. I would,drop,a,screw shot,for I but my default keyboard (the only one I can,get on here) doesnt see to have that option. Plz help
