I was listening to music no problems, then i encountered an issue with my laptop's sound driver so i had to restart. i load up Spotify again, go to listen to my saved playlist. all the songs are there but when i go to play them, i get an error saying "This song is not available. if you have the files on your computer, you can import it". i tried to go to my saved library, even thats doing the same thing. i closed Spotify, reopened it and see if that fixed the problem. nope, its still there.
