I have a PSP 1000 with CFW 6.61 PRO C and I recently downloaded Ben10 Protector of Earth. when you start the game it asks if you wanna create a save file. so I hit yes and it says accessing memory stick and it freezes and the psp turns off. I tried downloading different ISO's but the same thing happens. but the game works perfectly fine when I choose not to create a save file. is there any fix for this?
