Hi, I have found the problem, it was a case of permissions on the server. The serverstart file must be run as administrator otherwise it cannot write the NPPL.
You must be busy as it took you 6 days to answer, not sure that is much use on a game where we play all the time.

By the way if you are thinking we are not serious gamers, we have three in the server, one of them has completed everything. He has hollowed out a mountain and put base in it, completed every level maxed out level read every book. Might be a usefull fella for you shoulf you need any testing done.
Great game by the way.
