I tried this and I'm still unable to connect. However, instead of it being a problem with the outdated client, it gets to the "Logging in" page then says "Disconnected by Server. Could not connect to default server, please try again later: java.net.ConnectionException".
Also, my friend said he was able to connect to the server when I told him I was having connection issues which lead me to believe there was a problem on my end.
