The game files (including all the graphics) are stored on the computer. If the computer you logged in from didn't have Krokotopia on it, then you'll have to wait until enough of the area is downloaded to that computer before the game will continue.
If you can't log on and/or get to Krokotopia on that wizard from your usual computer, send in a ticket to Support.
