Emulator Not working regaurding memory

[Bozzhant]

I loaded Fire Emblem: Path of Radiance through an external disc drive, and the .iso shows up and works fine. However, when I start it up, It says "Memory card slot A needs to be formatted, would you like to format?" I select "yes" , then it says something along the lines of "The card has not been formatted" Then I load MemoryCardA.USA.raw into the memcard manager and I get the B T C I B F blocks, and the amount of blocks remaining, but then I load the game again, it doesn't work at all, and I get an error message saying "Dolphin.exe has stopped working, Windows is checking for a solution." I've redownloaded the emulator once and the exact same thing happened. Please help.
