According to Vincent, the client some of us are using or all of us are using had something removed that wasn't supposed to be removed.
He has fixed this and now we're using a new server client.
You may find the download for it here, or you can find it in the global announcement titled "MapleInfinity Client & v97 Setup Download".
We apologize for any inconvenience.
Client download is now up!

You need WinRar to extract the Client in order to play!
