Awesome ! You are right it works.I don't think the 10.1 patch was made for version 9.1.1. It was probably made to update version 10 to 10.1 because the file and folder structure is different in the 10.1 patch then it is in 9.1.1.
I downloaded version 10.0, and then I apply the update 10.1 and I finally have access to the rest of the game.
Thank you.
