I'm sorry to have surely created a thread for something that has been asked dozens of times but due to a lack of time and knowledge about this field bare with me. I have a Nokia Lumia 520 GoPhone. I used it for awhile for the sole purpose of getting achievements on the fly and it worked well for awhile. Due to the consistent delistings of games I decided to by the mini SD card but then realized you apparently need Windows 8.1 to enable saving games to the card. I did so and now I cannot seem to connect anymore. I can go to games and see my collection and I can DL new ones but whenever launching a game I get an error message. I've tried the date/time trick to no avail and nothing is continent on my privacy settings on Xbox.com. Any ideas? This is extraordinarily frustrating.
