We have attempted to do the installation but when she gets to step 5 the directions are not complete. She gets a message that says she is not white-listed. We aren’t sure if she won’t be able to access it until the camp begins and we have done everything correctly or if we have something incomplete.


The server won’t open until the planned time. If you can start a new world with the mod installed then you are in good shape!

Get it all installed, but then when creating new world to see if Turtle/Computers are in inventory, I get the message “closing down internal server…” and then Minecraft crashes. Help?


Backed up .minecraft folder, found Youtube video that said delete options.txt file in .minecraft folder, went back in to the game, worked fine.
