MY CLOUD HOME

So after shutting down my 4tb my cloud home, on start up plex decides not to work, cannot be configured etc etc, unless I delete the entire plex folder from the server, only then will it allow me to re enable, and then it starts from fresh. Any ideas, or do I need to bin this piece of junk.

after paying for a plex pass, it worked for one measly day. does it mean i have to pay for authorization everyday and do the same for all my media?
