wont recognize my memory card
 

I have a Blackberry curve 9360 and yesterday i was playing the game 'brickbreaker' and a pop up came up saying 'memory card disconnected'. I have tried removing it, blowing into my device incase dust got in there. I have also tried removing the battery and that didn't work.

I also put in a different memory card that i know works and it didnt recognize that either.
