Can't login

[user-removed]

Hi to all. 

I was trying to disconnect Facebook from my Spotify account. So, i went to Preferences and Under Social I've disconnected from Facebook. The problem is that I've create this Spotify account with Facebook and now I realized that I can't unlink the two services. 

Anyway, now I can't login. Not with "Login with Facebook" or with email and password. 
I realy don't wnat to loose my Spotify Account. It would be terrible. 

How can I login and reconnect Facebook again?

Thanks, 

Best regards
