Remoting Configuration Question

I'm a Remoting newbie. http://www.microsoft.com/downloads/...;displaylang=en I dowloaded the sample Remoting application from above and have been struggling with the configuration aspects of it. This is the case with all the other Remoting applications I've built in the last few weeks. Everytime I excute the Client application, I get a Serlization/Deserialization security exception. Yes, so I checked the google and got the fixes and all the brainstorms, but i'm still stuck. Please tell me if I'm missing anything in the "Client.config" file below - Thank you very much! God Bless You! :)
