Launching and playing the beta I have no issues whatsoever. Whenever I close the beta out I cannot launch any app on my Xbox. I get error 0x8007139f on every app or game. I've tested this on three separate systems in our house. Both mine and my husband have the alpha ring of the Xbox beta, my son does not have the beta installed. On both alpha versions the error occurs, not on the normal version. We tested this further today by playing on one then launching a game after closing the beta down. I had the error again, my husband who wasn't playing the beta but another digital game launched a new game at the same time with no issues. I'm not sure if this is the place to submit this to, Xbox sent me here. Hopefully it'll help someone out.
