Thanks!! It works

Hi, I have a problem. When i delete a platform and i restart launchbox, the platform comes again to the list.. if you open a rom it doesnt work now, but the platform is impossible to delete, it always come to the list again. In some platforms I have all roms duplicated... Super Nintendo, Arcade,... I dont know why Im new in launchbox, i have bigbox and emumovies account. Thanks for your help ;)
