Please provide any additional information below.

v0.5.5 is for 1.4.7 R1.0+

I'll downgrade it for 1.4.5 in the morning.

After reviewing the log you posted, I found this:

2013-02-02 16:32:39 [INFO] This server is running CraftBukkit version git-Bukkit-1.4.7-R1.0-b2624jnks (MC: 1.4.7) (Implementing API version 1.4.7-R1.0)

It's the right version of bukkit, so please be sure that you're using the correct version of Java (Plugin compiled with JRE 7, Unsupported major.minor version 51.0 means you're most likely running JRE 6.)

If it still won't work for you, let me know and I'll see what I can do for you.

Your right that im not using JRE7. Would that matter? If thats the problem feel free to close this ticket. Sorry Im quite new and didnt realise i'd have to get JRE7 for the server.

@SlappyTheSeal: Go

Well it's a common error, most developers automatically assume people have the latest version of Java installed. However, you can try this:

I compiled this using SE 1.6 instead of 1.7.

Let me know if it works since I can't test it (All of my servers are JRE 7)
