dolphin will not load games?

[Sayr]

Hello -

I just downloaded Dolphin for the very first time. I am trying to play Twilight Princess on it. However, every time I try and load the game, it loads up another window, one that is black with the Dolphin logo, which gives me a wait signal for maybe fifteen seconds like it's trying to load, and then the window closes and nothing else happens. What could be causing this? What am I doing wrong? Thank you!
