the debug tab on the bottom says:
"no flashplayer found in UIObject: Update"
and
"Flash load fail: "C:\program ... \Public\GUI\subtitles.swf"
this error appears to come up 10 times per second in the debug tab.
also i cannot close the editor. only via task manager.
I got this at first, when I set the game data path as the primary directory "Divinity - Original Sin" instead of the "\Data" subdirectory. Once I changed it and restarted the toolkit (although I had to force close it via Task Manager, as well), then it worked fine.
