I dont know what happened but when i logged on to BNS today it security alert keeps popping up. This happened on another game i played but it didnt affect it. But now the xcode thing came up 

i deleted that file because i had to to that to another game as well. so i thought that was the issue, But now the launcher keeps says update error and i know its not my internet because i just got to updated. Can some one please please help me. ASAP.
