Black screen? Freezes often?

I dont know why but every time I finish a game, it the freezes. I close the game and try to open it up again. At first it looks like its going to work, but then its just a black screen with the music playing :s Otherwise, its an ok game. Gives me my fix, but Id recommend just playing the actual card game!!!
