Playing with it a bit on my laptop here at work. I did notice the first time I fired up creative, windows firewall asked if I wanted to allow it. When those popups came up did you allow it? If that’s not the issue, then what I did to clean my creative out was…
in this folder \Boundless\server\creativeworlds
I deleted all the folders 1,2,3 etc…
in this folder \Boundless\discovery\creativedb
I deleted all the contents…
Then I went back into boundless and did the process again and took a video of it. You might want to start with a clean slate, and just try making an empty flat planet first to make sure you can get that working before attempting the download / copy / paste worlds.
Edit to add:
The video only captures the game window so for info…
When you start the creative server there should be a popup with the title like this
and then when you start the world there will be another popup like this
Make sure you leave those open and running in the background while doing creative world stuff.
Edit2 to add the list of steps I followed:
Screenshots from my tests at home included in the steps… press triangles to show.
6. **Swap to Creative** .
It will say “stop” if the world is running, which means you can swap to creative.
