Im really new to all this, but here is the problem. I have set up a custom 3x3 grid map but only have two of the nine grids. The center grid is my home server. The second is the center north grid. A friend and i traveled too the North grid no problems. Then he logged off for the night. I traveled back to the center grid and logged off. This morning i get on put in my password with no problems. Then my friend try to get on and it keeps saying "invalid server password empty field." ?
