I bought The Witcher 2:Assination of Kings around the end of December. I downloaded/installed it right away. No problems. I launched the game, picked New Game, picked "Easy", and it started, after the King's assassination video, with Geralt standing on a dock, with wet boots and heading to the Arena. Then I redownloaded it to one of my external drives, but when I launched that one, it started with Geralt in prison being beaten, then questioned. What's happening, why did I get different beginnings? Please help!

The "wet boots" part is the tutorial. You are asked if you want to play the tutorial, so I guess you accidentally skipped that the second time.
