got my sonos all set up at home a while ago, all working perfectly with spotify and napster. i ripped all my cds to FLAC and added them to my library and everything was fine with much improved audio quality.
when i tried to play the tracks from my library they no longer play and it says the computer (which the files were downloaded from) no longer exists? and no matter what i do, i cant get the tracks from my library to play anymore? anyone had these issues? cheers

Is this a home network problem rather than with sonos? Can you look at the whole network from the PC and see if it's all OK

hi mate. just got it sorted now. windows firewall had found it and was blocking sonos from taking music from my pc. i clicked allow access and all tyhe flac files are now in my library. cheers!
