You ned to add one empty line at the ending of the "ascent-realms" config file. Just open it with notepad, scroll down, and add that empty line.
Now I'm having some problems with this too, I managed to create my server and Log in with account name admin and password admin, I see one character. When I try to log in with that character, I get error "Login failed". And when I try to create another character, I get disconnected... So I can't play at all. Any idea what is going on?
