Oh boy, after three months of dealing with that last error code, now I'm getting another one:
"There is a problem communicating with an Xbox service. Please refer to error code 002408."
I can't play the daily challenges on Minesweeper, Mahjong, Solitaire, or Taptiles, nor some of the other games. It may have started after my computer restarted to make Windows updates.
C'mon, Microsoft and Xbox, get it together!
