I Brought 2 dsi's 1 each for my son & daughter they have been working fine then i connected them to my wireless internet & all of a sudden i cant play any games on them i'm not good at understanding things like this so not sure if ive done something wrong they keep coming up with the error screen telling me to turn power off & look in the manual but that doesnt help! Can someone help understand whats going on & have any ideas on how i can resolve this matter Thx x
