fail to calling webservice function

Hi
when I try to calling the Service on local is working fine.
when I publish on my testing account
http://user820.netfx4lab.discountasp.net/TestWebServiceTestPage.aspx#/Home
I get the follwing excption
An exception occurred during the operation, making the result invalid. Check InnerException for exception details.
at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary()
at TestWebService.ServiceReference1.DoWorkCompletedEventArgs.get_Result()
at TestWebService.Home.ws3_DoWorkCompleted(Object sender, DoWorkCompletedEventArgs e)
at TestWebService.ServiceReference1.Service1Client.OnDoWorkCompleted(Object state)


I also ask at silverlight forum

Have you looked at the InnerException property of the Exception? Sometimes you have to drill way down to find the originating issue.

Also, it sounded like this was the result of a webservice call. Have you tried hitting your service with the browser? This always helps me diagnose whether the issue is communication or server side.

It'd be something like:
user820.netfx4lab.discountasp.net/YourServiceName.svc

Just fishing for more potential info.
