Make sure the contacts on the bottom of the game are nice and clean, you can use a damp q-tip with glass cleaner to clean the contacts. Then take a dry q-tip to clean off the contacts.
I would also take a can of air and blow some into the slot on your DS where the game goes.
Now put the game in and turn on the DS to see if the game loads. If it still doesn't load then at that point try some other games to make sure they load onto your DS. If other games are loading and not that game then get a new FIFA Soccer 09 to try. If no games are loading then that means the DS has gone bad and you'll have to get a new DS.
