Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General Divinity Anthology Bonus:The Golden Grail code ???

I just noticed on the latest patch news the Steam DLC is now working.

But what about us with the Divinity Anthology Golden Grail?I just tried running the key on steam and it's still not accepting it.
I could have bought some extra skills with that 10% I've missed out on.
