Are you sure it's not updated?
If it helps, I bought the GoG version of Divinity, and refunded it citing the broken editor. I bought it from steam soon after. I did E-mail with Larian a few times, here is a snippet:

I talked to GOG about this and helped them identify the problem. The issue is that their version of the editor is really old, and they keep updating the game but not the editor. I informed them that they should update the editor as well because the old version will not work with the new data of the updated game.
They will fix this in the coming days.
Thanks for making this known to us cause it seems to have been lost for a month....
Cheers,
David

I'll let you know - GoG is issuing me a reimbursement which I will
use to buy the game from Steam network. The error I am having seems
to only occur to customers who have purchased the GoG version of the
game.
GOG was really good about issuing the refund - I was happy with the service. If you truly bought the game for the toolkit and the toolkit won't work then pursue this route.
