I was able to successfully open the Example.xaml file from the WPF ScheduleView and TimeBar
example. What I can suggest is to try to reinstall the demos and see if it helps. However the Silverlight demo shares the same code with the WPF one, so you could simple use the Example.xaml file from the Silverlight demo (I'm also attaching the file here).
Hope this will work for you.
