Hamachi IP address seems to be not working

Good evening,

I've been using Hamachi for some time to run my game (Minecraft) server but today I found out that it doesn't work anymore. When I start my server it will close after less than a sec because of this error:

*** FAILED TO BIND TO PORT!
 The exception was: java.net.BindException: Cannot assign requested address: bind
 Perhaps a server is already running on that port?

  and therefore the server won't work. I don't have any other servers running on that IP and the server will start normaly if I don't specify IP address but the game won't work that way. So I need the Hamachi IP address working to start the server and play the game.

Could you help me find out why it is not working please?
