No samples loading or played in media bay or file browser

I Have this problem that the media bay or file browser doesn’t respond on my sample library from my ineternal desktop drive. It used to work but now it won’t show my samples or play them. How can I get back to the basic. The media bay has so much options. I don’t know where to start. The file browser doesn’t has all these options but doesn’t work as well. Who knows the solution!!!
