Photon Server cannot Start

Hi all, I am a newbie to photon server. I followed the instruction on Starting Photon in 5 Minutes. When I start LoadBalancing as an application, the server starts for few seconds then it shut down and throw some exceptions. The exceptions are shown as following:

14536: 15:35:49.925 - Service is running...
14536: 15:35:50.181 - CounterPublisher:4 - PhotonRunning() failed. Exception:

I reinstalled .NET Framework 3.5 according to the post here but it doesn't help. Does anyone have ideas about this problem? Thanks in advance!
