Making a server

I got all the server stuff I want and it worked as a local server, but when I hook my laptop up to my wireless with my Ethernet cord, it keeps saying "Error, unable to run server. Another server is already running on that port."

25565

Help me :< is there like a program i can use BESIDES HAMACHI

@Lady GaGa
Do you have any 25565 ports on?
If no, then uhm.. try restart your computer.
Uhm, i'll tell how I portforward
Go to cmd
type IPConfig
look for default gateway
enter it on your web browser
go login
Portforward?

forget my server.

I found a server that is better than mine could ever be.
