Post the output of your Java console here. If you can get into private servers, and you are trying to get in a server hosted on your own computer, try it without verify-names. There's a bug on some systems re: joining local servers. Once you disable verify-names in the config try to use server.jsp?ip=127.0.0.1&port=25565 IIRC. It should be in the readme. Let me know if it works.

I'm back. Time to revamp this place now that there's no IRC for me.
Feel free to IM me. I'm here to help with whatever issues you may have, and would be glad to assist.
