I edited your post to remove the link. You also got a slap on the wrist that will go away in a month as long as no further issues come up. Don't link to sites that promote piracy.You should choose wisely the number you put in "Costume Slot" field, if that number is used by official or mod DLC the game crashes.
There are free slots for all the characters but as new DLC come out they are occupied by them.
The slot i choosed for kasumi (10) should be free, if the game crash with it, check if you have some other mod using it.
