DSi 300 in 1 gamecard keeps booting

Hi,





When I wanted to start a game on my 300 in 1 game in my DSi, it keeps booting. This is not only with one game but with all of them. I have never had this before and I do not know what to do. Can somebody help me?









Please help.

Thanks!





I did not find the right solution from the Internet.
