Connecting Problem

i have a problem about other person connecting at my server cos i can connect but they can' and i'm using loopback... please help me

Either Forward the Port or Use No-Ip ...
Look my guide in Mu Tutorials ;)

I have just set up a Mu S5 Server using a guide on this forum.

When i go to connect i get the following Error (In screenshot)
I've been able to connect and create an account in MuMaker
But i can't access the game - i've changed the Main.exe's IP address as well. It says Enter Your Account

Do you have MD5 turned on. I believe this would be a MD5 problem
