You need to use a program that can extract the zip file, like Winzip or any other zip opener.
Ohh ok thank you so much!
the lemonade and boardwalk are not unlocking how do i fix this??
Hello! Someone else had that problem and they fixed it by updating the main game. You can delete the older build, down the new version of OL + all the most recent DLC, and then put the DLC into the new "game" folder.
