@Baydang11 If you have the CAS Demo installed, please see this thread:

Otherwise, please run a search for EP11 , which is the folder for Cottage Livin. Open a File Explorer window, click This PC in the left panel, and enter EP11 in the search field in the upper-right corner. Wait for the search to finish, then make sure the full file path is showing under each result. If it's not, expand the window sideways as necessary. Take a screenshot using Windows key-shift-S and attach it to a reply here.
