litePeer.OpRaiseEvent fail to trigger OnEvent?? stop at Executing operation RaiseEvent ,need help!

Hello, I'm a newbie about Photon Server. I follow some tutorial to setup the LiteApplication and LitePeer step by step, however when I send the message with OpRaiseEvent(), there are noting happen... Image may be NSFW.
Clik here to view. . I try to check the log and find the log stop at Executing operation RaiseEvent. What's wrong with my code .... Image may be NSFW.
Clik here to view. . I can't find simaler question with google, really need help..

following is some detail:
