So I finally got my friends to install RPG-X and they wanted to play with me..
Thing is I made a server for "Internet" and we all were able to find it, but when we try to join it kicks us out.
We really want to play on the server one of us host, I beg for help.
As this is more of a technical enquiry than a noob report. I'll move this to the right area
A kick back to the main menu could be for many reasons, please could you follow the steps here - https://last-outpost.net/forum/index.php/topic,5446.0.html
Once you have the error if you post it here I should then be able to help you more.
Unfortunately without that error I can't really help as it could be anything from not having the map to issues with settings, the error will allow me to help you resolve the issue more quickly.
