Yesterday I was suddenly unable to play my music as seemingly could not be found. The only thing that has happened is for first time I allowed Onedrive to sync all my laptop files, and now I cannot see them on my C drive, just Onedrive. However, my C Drive seems still very full as though all my files are still there but I (and SONOS) cannot see them. I am at a loss as I’m not that technical.  

Thanks for any help with this
