I removed every plugin and it still happens it all started when I was using the ChatClear plugin and that plugin it has a command called /ccban which will ban a player I thought It would lock chat so I typed in /ccban MCBro911 and it crashed my game now I get the following message in my client:

I believe, since I've seen that before on my server, the server can't connect to the mojang auth servers and verify that you have a real version of minecraft. If you do have a real version, restart the client, log out and then back in. (make sure you've also transferred your account from minecraft to mojang at their site).
If you do not have a real version of minecraft, in the server.properties file set "online-mode" to false.
IE: online-mode=false
