If changing the address to what Halibut said doesn't work then make sure that your version of minecraft is set to 1.6.4 as the server is not updated to 1.7.2 because Craftbukkit and other plugins have not updated yet. We will update as soon as the other plugins and bukkit updates!
Hi! Sorry it's taken me this long to respond been out of a internet zone since Saturday! So I downgraded the version and I got it! Can't wait to start playing!
No problem!! If you have any more questions just post somewhere in the forums for now. still haven't finished setting up different threads for different topics yet.
