Your AR is Corrupt... Shut down the DS, then HOLD A+B. When you see the NintendoDS screen HOLD Start+Select WHILE holding A+B (4 buttons total). Your ARDS Should be white but eventually (Around 10-15 seconds) the AR screen will pop-up (This product is not endorsed blah blah blah.) when you get to the main screen you'll see that the codes have reduce to ZERO[(0) You RESET your AR] Then just go to the ARCode Manager and upload the codes... That should work...

WARNING: This WILL RE-START YOUR AR! ALL CODES AND GAMES WILL BE LOST! But you can just upload the codes/games via the ARCM

Sucks for me cause my ARCM dosen't recognize that its hooked up >.<
