You need to make sure that you are putting the .minecraft folder in the correct directory. It would help us a lot if we knew what operating system both of you were using. If you are trying to copy a .miencraft between operating systems, it likely won't work. Just install the LOTR mod on your brother's computer just you did on yours, seems the simplest answer.
