ok not sure where to put this question so here goes

I have a spotify free account and have been listening to music on it, but the last 3 nights it asks me to log on and I do with my FB logon... but I cannot get the main page up with the 'player' - where you search what albums you want to listen to - keeps on asking for spotify user name and password... I don't understand?!?! it worked fine before
when I go to reset password it takes me to the account page in spotify... I am logged in and just want to play some music!!!
I don't have a premium account and don't plan to get one

help please!
