anyone have problems playing animal crossing... ?

I've recently gotten Animal Crossing for the DS but it does not seem to work... it always says "data could not be retrieved, please turn off the power and re-insert the game" any ideas on what might be wrong ?

it can be the settings on emulation setup under options change the nds catridge backup media to auto
if there is no auto download this another emulator cause your emulator might not be the latest
