Your card is still alive but it doesn't support the new DSi firmware.
You'll have to wait for an update for your card which is less likely to happen.
Better you get a new card.
I'm actually really hyped about this one as Pokemon Black is one of my favorites.
And i hope it'll be a completely different region which is larger of course.
