problems with Calendar sample app

I downloaded version 1.2.0.1 and have been able to get the Friendbook 
app to work, but cannot get the Calendar app to load the initial form. 
I continue to get the following error. I am using the localhost URL 
http://localhost/Calendar/Default.aspx . Any suggestions?

Controller Maverick.Flow.ControllerFactory+NullController specified 
view "NO CONTROLLER DEFINED", but no view with that name is defined.

Line 50: 						controllerType 
= ((ThrowawayControllerAdaptor)this.controller).ControllerType;
Line 51: 					}
Line 52: 					throw new 
ApplicationException("Controller " + controllerType.FullName + " 
specified view \"" + viewName
Line 53: 						+ "\", but no 
view with that name is defined.");
