I tried to search for the answer but couldn't find it...

Anyway, my problem is my Ghost in the Shell region 3 (the umd) game freezes immediately after the Sony screen while the game is loading. The power light flashes and then the psp just turns off. I'm not sure if the umd is defective or if its some other problem. It does the same thing with or without the memory stick inside the psp. I don't know anyone else who has a psp so I haven't tested it on another psp. I'm using firmware 2.71 SE-A. Any help would be greatly appreciated.
