It seems you had spaces inside your path to the game, so something went wrong. Rename your EBOOT.BAK to EBOOT.BIN and put your game eg. in X:\GAMEZ\_BCES01175 and rerun the fix. After it's done you can rename it back to what it was.
I'll look into changing the fix, so you can simply put it into the game dir and run it, instead of dropping the game folder onto the script, which would avoid such issues.
