The type initialize for ‘Microsoft.Practices.ESB.Configuration’

Hey Friends,
I have yet another Microsoft Visual Studio error message. I could figure out, that it could be an issue with ESB.config file, but not sure how to solve that.
I am getting issues on selecting the Orchestration on the Itinenary Service. The error is shown below. I tried to modify the ESB.config on my other PC but it still the same.
Please help.
Microsoft Visual Studio
The type initialize for
‘Microsoft.Practices.ESB.Configuration.ConfigHelper’ threw an
exception.
OK
