costum stories problem

[paperboat]

i have downloaded 2 costum stories for amneisa but i dont know if i have done it the right way, i have the amneisa costum story installer but when i try to open it a error window comes up and says: "error! please create a costum story before trying to create an installer"

the thing is i dont know a s**t about computers, mostly i ask my big brother for help, he helps me but just gets mad at me everytime i ask for help which just makes me mad at him and dont want to ask him for help anymore, so now i atleast tried to fix this for 1.5 hours but nothing happnes so please can somebody show me a guide how to fix this piece by piece for WINDOWS 7.
