Yay more fun errors! I honestly have no idea what any of this means. Since this morning this error has been spamming my console. This is just one section of it. I'm pretty sure it repeats. I tried uploading the literally 3,000 line error to pastie but it was too big.

It almost looks like you have a second instance of your server running already. Have you killed the java process and tried again, or rebooted the computer?
After you have done that, if it still doesn't work, the only advice I can give you is changing the port of the server. (Going into the server.properties and changing it)
