Fire Emblem PoR Help

[moshingpuppets]

So i start up path of radiance for the first time and it works fine. After i'm done playing it i hit escape and end the emulation. When i go and try to start it up the second time it doesn't work. Every time i start it up it says dolphin.exe has crashed. So what is the issue here? Also, when i first start u the game it says the memory card is corrupted and i need to reformat it. Please help.
