I'm using a Hacked Client ATM, and it mentions some stuff about Clients and Illegal, but i'm also posting this in the Hack topic, Thanks.

you could be missing a file that supports the client? possible delete your .Minecraft folder and than Run minecraft again to get the files again. After that try using your hacked client again. You should make a backup of your Texture packs and servers.txt if you have any.
