For about 2 weeks ago my Spotify Unlimited just disappeared. It happend when my friend wanted to login to his account. The wierd thing is that all my playlists are gone and it says i got Spotify Free but have a current subscription every month. On my account it says that it has drawn money from my account today (05/03/2012).
I tried to log out and then in, but it still the same problem. Hope you got a solution! :)
