Don't use this "hack", i just reseted my rank ect. this way and and joined a game with the new level, 1, and suddenly I was kicked "Notification, cheated spotted" -.- got me banned it seems :-!
this isnt a hack and this is the most known way to reset your rank. some people do use the delete steams local player stats button of EAM which deletes exactly the same files as this tutorial sais. you are banned because of a hack like a rankhack, esp etc.
