World Creator 2, World Creator 2022.x and World Cretaor 2023.x require your firewall to have following ports open for ingoing / outgoing connections:
- TCP port 5565 for World Creator 2
- TCP port 5566 for World Creator 2022.x and World Creator 2023.x
For this, you need to edit your firewall settings manually (if you use your opertaing systems' firewwall, then the World Creator installer should have taken care of it already).
If it still does not work, delete the entire folder [USER]/documents/World Creator/versions/[VERSION] and try again.
And If it still does not work even after that, please check your system or network for connection blocking system or restrictions! If really nothing helps, please contact our support team.
