hey! you get the copy protection when you try to play a game because you dont have the games owner account on your ps3. i recently created a account on my ps3 so i could download calling all cars.1 of my buddys gave me his account details. it played untill i deleted the account i created to download it. i then downloaded it again but cancelled when it started thedownload. works fine now as its verified again to his username.
so for the games that get this msg when you download via proxy then that is why.you have to have the games holder account on your ps3. i got, super rub dub, gripshift and suduk working but nothing else. go puzzle just stays as a demo for me. warhawk works great of course. you dont need to create US or EU account to play games. i downloaded cac on my EU account and works fine.
