Aide serveur sur mon pc

[SuPrAZzAt0M]

Bonjour, je viens de creer mon serveur directement sur mon pc. Je le lance, tout se passe bien, mais lorsque j'essaye de le rallumer avec le :" Start.bat ", ça ne fonctionne pas et ça me dis dans l'invité de commande :
[15:02:51] [Server thread/INFO]: Starting minecraft server version 1.7.10
[15:02:51] [Server thread/INFO]: Loading properties
[15:02:51] [Server thread/INFO]: Default game type: CREATIVE
[15:02:51] [Server thread/INFO]: Generating keypair
[15:02:52] [Server thread/INFO]: Starting Minecraft server on 87.91.153.9:25565
[15:02:52] [Server thread/WARN]: **** FAILED TO BIND TO PORT!
[15:02:52] [Server thread/WARN]: The exception was: java.net.BindException: Cannot assign requested address: bind
[15:02:52] [Server thread/WARN]: Perhaps a server is already running on that port?
[15:02:52] [Server thread/INFO]: Stopping server
[15:02:52] [Thread-4/INFO]: Stopping server
