I just launched my 1.0.1 server for the first time and it said: " [WARNING] Perhaps a server is already running on that port? " The only thing is, there is no server already running on that port, so I don't know how to stop it from running. I had this problem before (in 1.8), but then I was able to log in on the server and stop it with a command. Now I can't see the console, nor can I log in. I'm running Craftbukkit 1.0.1-R1 on a Windows Vista 64-bit. I hope someone can give me some good advice. P.S.: Changing the port (to 25566, for example) doesn't help. It works, but Minecraft won't recognize the server.
