Did work - now won't!


I have an M8S Quad Core Mali 450. I have no idea what this stuff all means but I've had it for about 6 months. I've never chosen a source before that was titled streaming but did today. Since the program finished I could only get out by turning everything off. Now I get it started again. I can view the My Apps icon and Kodi icon but clicking on them does nothing. Can anyone help me without suggesting I learn more about the system. Tkx.
