I'm trying to set up a HKMP thing as per Fireb0rn's tutorial, but me and my friends get stuck on the "connecting..." stage of ItemSync. We have tried different mod launchers, different server URLs, installing and uninstalling the mods...
I then downloaded the MultiWorld mod hoping it would be a possible alternative (I do not actually know what it does and wether it is a potential alternative to ItemSync), and managed to connect but failed to launch the game (some error happened; Modlog.txt will be attached).
We are playing on windows.
