[Minecraft] Problème serveur, port !

J'ai un problème au niveau du port je ne trouve pas quel autre programme l'utilise:

[INFO] Starting minecraft server version 1.5.2
[INFO] Loading properties
[INFO] Default game type: SURVIVAL
[INFO] Generating keypair
[INFO] Starting Minecraft server on 25.14.34.181:25565
[WARNING] **** FAILED TO BIND TO PORT!
[WARNING] The exception was: java.net.BindException: Cannot assign requested address: JVM_Bind
[WARNING] Perhaps a server is already running on that port?

Et voila mes option du fichier serveur:

#Minecraft server properties

allow-nether=true
