Lol.. you screwed up.. your move command was wrong and you overwrote the PS3 config one :P Basically means your stuck if you don't know what your doing as its farrr too late at night for me to want to help you =x

If you want to do it manually by opening blight_input.conf in leafpad (as instructed), here is the proper only for PS3 controller. You can probably copy paste if you want. Just open this in browser and copy:
