World editor don't work

Hi there! I follow the steps from the guide but the world editor doens’t work correctly.

I can’t see anything after add a new terrain. Even the “preview” for the items doens’t work.

I add a video.

Thank you!

Buttons don’t often work “right away” but require assets to be loaded. http://www.grimdawn.com/forums/showthread.php?t=37791

This is good news because you can replace the graphics in the game if you want.
