Quick Question about saved games
 

Hi, I just now bought the entire Tales of Monkey Island series over Steam because of the deal they're running. However, I have previously cashed a coupon for the first episode free during the special run during Talk Like A Pirate Day.

My question is, is it possible in any way to move my save data from the game received through the Telltale site onto the steam game, or will I have to start over?
