Well I attempted to make a server using Hamachi I believe I did so successfully, because everything was going according to plan but when I tried to connect it said, "The server responded with an invalid server key.". What do? Yes I have Hamachi open and yes I have the server on run with the Minecraft_Server.exe still open too. I can connect now but for some reason now matter how many times I change the seed I spawn in water and there is no land around. Thanks, Dream.
just keep trying different seeds. You could also just take a map from single player if you have any. Do you want a flat map or a naturally generated? I can send you a map if you want.
