Help me im new and i cant work this server pls :(

I cant start up Summerstory its not offline i know it because i tried EVERY v62 server and it still wont work! after gameguard finishes loading a pop-up shows saying
"We are unable to connect to the login server do to a server check, a firewall block or other network issues, Please check the MapleStory Homepage for ongoing server checks as well as your firewall setting" but my firewall is off Pls help me

SummerStory IS actually offline, the website just says otherwise. With other servers, are you putting every file included in the .zip file? ALL files are required.
