Minecraft Forums

So, I'm trying to run a server for the first time, and I followed a guide that's stickied at the top of the page, the ports are forwarded and everything, but when I attempt to connect, I just get kicked. I'm not using the .exe, so the cmd window says that my ip needs to log in. I know it has something to do with the server.properties file, I just don't know what to change. I've read the faq, and that didn't work, so... Any help is appreciated.

Thanks,
Carnax

EDIT: Minecraft also crashes after I try to connect...
