Make sure you have Updater.jar in the same directory as Game.exe. If it still doesn't work, redownloading the rar might fix it or it could be a problem with a lot of people trying to use it at once.

The second thing doesn't really sound like a problem with the game. I would try Googling for that DLL because it's not one included with the game.
