If I am not mistaken just change the current user on fhp file to the new user, and place it there, and it should work for you. ^^
You could try this: Ask your friend to give you the actual files, trust me, it works. c: Then place those files into any preset folder number you want. After that, open up the game and load it on preset maker. When you're happy with it, go back to your home screen and make sure you write your new account username in the username box. Finally, go back to preset maker and export the preset. c:
Hope this helps!

Or do this one cause I believe this might also be better, and more simple for you my dear. xD
