Action replay problems


i have an action replay ds and i have been playing pokemon diamond.
it has benn fine until a while and it has suddenly stopped reading.when i turn the ds on with the AR it says no game inserted and i cant usb it to the PC either

  1. Try resetting the hardware by following these steps: 1/ With the console powered off, hold A+B.
    2/ Power up the console while still holding A+B.
    3/ As soon as the Nintendo screen is displayed, before our screen stating this product is not endorsed by Nintendo, press and hold Start and Select while keeping hold of A+B.
    4/ Continue to hold these buttons until the Main Action Replay screen is displayed, then release. Your product is reset, and will accept codes once more.
    I do not have credit. these instructions were from (creators of AR). then try uploading them on the computor.
  2. i have the same problem. i try to play my animal crossing wild world and it will load up, but wont even start the whole game. a black screen appears. i have the black lines, and most or part of them wiped off. i think its just dirty, or badly scratched.
  3. turn the ds off and as it is booting up press a+b then when the ar screen starts press a+b+ sel+start
