just delete all your profiles, there will be a few of them. you will know if you have deleted them all because when you start et it will ask you to create profile. as long as you have not deleted your etkey it will not affect that. if you want to go back to the default cfg, just type in console /exec etconfig.cfg if you do that command for etconfig, do it before you create new profile otherwise you will need to create it again, as it sets your name to etplayer.
