Someone please help! ProtocolLib will not work! This makes my server have lag and a lot of plugins do not work! Here is the console: http://pastebin.com/sCJr4V9G AND YES I HAVE DELETED THE PLUGIN AND RE INSTALLED IT!
the plugin may not be built for your version of Craftbukkit. I suggest updating one of the two, or finding a different build of the plugin. perhaps a dev build?
