Launching X1 does nothing

I looked in the Windows Event Log and found two events occur every time I try to launch X1 beta. The first one reports the source as .NET Runtime. Here are the event log entries:

Application: X1.exe

Description: The process was terminated due to an unhandled exception.
Exception Info: System.ServiceModel.EndpointNotFoundException
