I just copied my saves and settins (everything in My Documents\Larian Studios\Divinity Original Sin) folder so when you "skip" you can still play, just come back later, create a new profile and use your key, then copy everything back and all saves and settings should work.
At least that's what i'm hoping, lol
Good idea but I am not gonna try it. I want to be 100% sure all is as it should be so I wait, hoppe it will be soon.
