Minecraft server help.

First of all, sorry if this is in the wrong section, but this is the only Minecraft section I've seen.

I can't get my minecraft server to run. I've por tforwarded and everything but it doesn't work. It says:
"[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?"

I might have port forwarded wrong or something. I have a linksys router. Post here if you can help me. Thanks.

 

Check you did the ports correctly, and reinstall Java whilst making sure you have the latest version of Java as well.

 

Yeah I'm pretty sure I did the ports correctly, and I just redownloaded Java. Still doesn't work.
