There was a problem with the latest update to Labyrinth I/O; the omission of a config file prevented it from starting up. I have fixed this now. I've also updated the web version, changing the renderer to something that will run a bit better on certain machines and tablets, so if you found the web version was running slow for you now, try it again.
Sorry about that!
