Hardware 3DS won't read games

[AntnioMoura]

Hi guys!
I have a problem with my 3DS.
Yesterday I was playing Pokémon White 2 on my 3DS and then i remember to play Kingdom Hearts: Dream Drop Distance.
Then I turned off the console and take the game off and put the KH:3D.
What when i turn on again and the game is not reading?Now no games i have read.
Can anyone help?

Use a q-Tip or just blow in it without spit.
