I did that, and it worked for a few times. But then it won't open and comes up with the same message as the one above, I have tried to extract all files again but the game still won't open. In this case, what should I do?
Extract the files to the same ddlc folder and after you extracted it, The game or "application folder" should appear with the icon. That means your game has been extracted and available to play..ALWAYS WORKS!
