HELP!

that means you didnt buy the full game
you need to buy the full game to play survival multiplayer games
but you can also play classic ( but i dont know to go there , wait for someone from classic to respond )

You're going to have to purchase a premium account here:

http://www.minecraft.net/store

Then register with whatever username you wish to choose (something that is appropriate at least), after doing so you'll be able to log on.

You can player the classic server for the meantime:
