so i wanted to activate Catwoman Bundle pack in arkham city on ps3 and i did with reactpsn , you know i did all the steps i installed the pkg then i created a user named aa then i launched reactpsn , the name of that user was changed then , but i wanna ask if i can remove that user now + if i want to install another DLC how to do it for the second time ? Should i repeat the process , will this delete the prevoius DLC or what ?
