About a PS3 Game GW1

Hello, I would like to play the game GW 1 on PlayStation 3, but I can't log in, I changed my nickname on PS4 but it worked on another nickname before, I don't know, I'm doing something wrong? if the servers are broken I would ask for help I don't know link the PS3 / PS4 account with the EA account greetings and please help quickly (I know that GW1 is not updated, but I am asking for help I really want to play this game and platinate it because they said that on PS3 will turn off servers).
