[Haskell-cafe] Conal Elliott's Vertigo, anyone get it to run?

I tried to run Conal Elliott's Vertigo demos, on 3 diffferent XP boxes; it ran on none. The error is "Common Language Runtime Services - Appication has generated an exception that could not be handled. Process id=xxxx, Thread id=xxxx". Any suggestions? http://conal.net/Vertigo/ John Atwood
