Im having problems with a ds game right now and i really dont know how to fix it. When i insert the game and turn on the ds, everything goes fine untill the game finally loads...Theres an error message that pops up on the touch screen saying "data could not be loaded. turn the power off and reinsert the game cart." this is happening with nintendogs. The game worked fine then this happened to it today i believe. any help would be much appreciated.
