Issue with Spotify on MacBook Air

Hello my name is Noksu.

I'm having trouble with Spotify on my brand new MacBook Air. Ive installed the app and log in with my account but all my playlists are gone and it won't play any music. When I google it the solution that comes up is to edit the hosts file but the problem for me is that my hosts file is empty except for a few lines with my own ip adress etc. so there is nothing to edit. If anyone has a different solution for this I would very much appreciate any info.

Thanks
