RUN.bat is trolling me. Perhaps a server is already running on that port?

[WARNING] **** FAILED TO BIND TO PORT!​

[WARNING] The exception was: java.net.BindException: Cannot assign requested address: JVM_Bind​

Help me dang danggit​

Solutions I did by myself:
Restarting the RUN.bat
Restarting whole computer
Checked that I'm not running any servers

PS:
I made a similar Minecraft server is Australia but when I move to Malaysia, this started happening. Why!?
I don't know the Password and Username of my router

 

Make sure you're not running more than one instance of Bukkit. Try changing the port in the server.properties file too.

 

I did, nothing happened. I changed it to 2556(5),(7),(4) nothing worked

 

Where's your server hosted?

 

Make sure server-ip is blank in server.properties.

 

Oh yea, if you're running from a server host, then there maybe a chance that some people are using the ports you're trying to use.
