Connection Lost : End of Stream

I'm having problems connecting to my own server. I'm a newb, so please forgive me. As far as I can tell, I edited the files correctly. The server loads fine, I just can't connect. Both are the same 1.5.2 , so they should be compatible. Not sure what else I am missing. My kids love this game, so I'm trying to run a server to let them play to their hearts content. I also run a UO Server, so I thought this would be easy, I must be missing something simple. I did the port forwarding correct, so not sure what else there is. Any help would be greatly appreciated.
