I installed 1.15 with add-ons. Single player works fine by executing doomsday.exe. If I execute doomsday-server.exe in my Windows 10, nothing happends. I´m able to launch doomsday-shell.exe and I there start new server, it thinks for a while and then I get "no playable games available".
I´ve hosted doom multiplayer games 2-3 years ago and I used shell fine, but now I see everything has changed. This is no help: http://wiki.dengine.net/w/Shell_Help
