This general error is not really very helpful. In general you might have some more luck by enabling logging in your service as this usually gives some more pointers as to what is going wrong, as this error gets thrown in many situations.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
