Cracked Server Won't Start!

OK so I followed Dakota's instructions n how to start my server. The minor question is does the server update on its own and when? The big thing is when it finishes preparing the spawn point i connect and when I connect Minecraft says its the end of the stream and the connection is lost on the starter. This happens every single time I try. If I'm able to fix this Hamachi is this:

Name: LyuuCraft Server
Pass: minecraftftw

the ip is 5.238.107.108 or 5.238.107.108:25565 I don't know which I should use.

Also, if you are a certain Numbing_Cookiez who used to be on Crusader's server(Dimi4el Server Minecraft or Dima Server Minecraft, remember?) please join my server cuz I am Spark!

The server doesn't update by itself.

Can you give more details?
Post your server.log and server.properties.
