Most likely, because the code you entered is incorrect. If even one letter or number of the code is wrong, the code won't work. Make sure you have the correct code, and insert it into your Action Replay again.
If your action replay is not working after you type in a code then the person you got that code from is a bad person with pokesav. He makes codes that mess up your action replay. BEWARE!!!!!!!
there are some but there to long and thay dont work.

IT makes the other action replay codes work.
you probably need to udate your action replay for the code to work.
