I have a problem too : I tried recently to use the Divinity Engine, but after some walls and a door placed, the game crashed, and when I launch it again, it say "failed to parse dockpanel.config", and then I cannot move nor place anything.
I tried to uninstall both game and editor and install them again, but it doesn't work.
Has anyone a solution ? I didn't found a file called dockpanel.config neither.
