Unhandled Exception: System.ServiceModel.FaultException: The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs.
initially i was able to use the tool.. not sure why this happened...
i found the below forum link
then followed the below and it resolved the issue..
The error seems to originate from CRM not being able to find theMicrosoft.Xrm.Client.dll file.
After some fiddling, I fixed it by copying the file from theSDK\bin directory to CRMWeb\bin directory.
