Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General Kickstarter reward or version issues? Inhere!

I purchased the CE version of the game on steam for a friend of mine and I to play, when we both go in game, he has a different version of the game than I do?

1.0.37.0 - Me
1.0.36.0 - Him

Any ideas what might cause this and how I can get this fixed so we can play together?
