Hello Tracy, how do you add the files to your client explorer? are you doing right click , and then Add files to client explorer from client explorer?

Thank you for your reply. I clicked "Go To" then "client explorer", chose the folder where the files have been saved, click "include the subfolders", then ok. showing "adding files to the database". Today, it showed another error message after I run it again. Please see attached. Your help is much appreciated!
