It loads nothing from a Mac

This application is great on Apple TV and iOS, our tool to read the movies from our server.
However, on the Mac, it doesn't refresh the content, read anything at all from the files, while the server and its folders ARE in fact available.
UPDATE of past review: the application has been vastly improved compared to its past versions, all functions work properly. Now just a little speed improvement here and there and will be 5 stars then.
