R4i error message

I have an R4i ver 1.4 and have downloaded the newest Kernel V1.43b and the DSI has firmware ver 1.4.1U and it was working wonderfully for a few days.Now all the sudden when you go into the DSI menu that shows the wrench, camera and the picture for the game you have in. The picture has changed from Star wars lethal alliance Ubisoft to Miami Nights 3D Ubisoft not sure how this happened and my son says he does not know either (he is 9 yrs old) When you click the new icon you get the following message....Error is - An error has occurred. Press and hold the Power Button to turn the system off. Please see the Nintendo DSI Operations Manual for hlep troubleshootingI have formated the Micro Sd 2mb card and started from scratch still no success, I have formated the system memory still no successdoes anyone have any idea's?? :'(
