I bot Divinity 2 when it was new on Impulse/Gamestop version of Steam. Same for the expaintion flames of vengeance. Now that I have come back to play the game a 4th time. I saw their was a Directors Cut and it was free for people who already own it. Yet I can not figure out how to upgrade my game. Impulse says I only own flames of vengeance.

Can someone help me?
