Hi west china! How did you manage to get it to work? I get the same error as in your video, only I'm using 127.0.0.1 instead of localhost in my config.wtf and it still doesn't work.
Also, I saw your message on playing with a friend via hamachi. Did you manage to get it to work?
If not, here's what I'd do:
First off some people told me to use radmin instead of hamachi because "it's more stable". I don't know if that's true or not, but try that.
Secondly, tell your friend to copy your hamachi/radmin "IP" and use that as the SET portal and SET realmlist instead of 127.0.0.1
127.0.0.1 is your own local IP, but your friend has to connect to your hamachi IP, not his local IP.
To get your hamachi IP tell your friend to right click your name in hamachi/radmin and select "copy ipv4", then paste that into the SET portal and SET realmlist in his config.wtf.
Also, the server you download from NalydBE is configured for local use, so your friend will probably not be able to connect to you. You should compile the core with the global settings, or maybe you could try setting your realm's IP to your hamachi IP, but I don't know if that's going to work.
Oh and one last question, in your video you had an english client, but I can only find french clients. Where did you get your english client from?
