How do I fix my DSi action replay?

How do you fix an action replay dsi when it tells you to insert the game but the game is in?

• Answer:

  I always blow in my ar and game card whenever i insert into the ds, but my New Super Mario Bros game has problems. It wouldn't recognize it, i did something to the code manager, and all of the sudden it worked. I used one cheat, it worked, then glitched out, as expected to happen occasionally. i turned it off and back on, and it hasn't recognized the game card since.
