Help with -- Spotify for Android?

I can download and open spotify fine. I have an account already that I use on the computer. I log in with facebook. Now, whenever I try to log onto spotify (on my phone) I attempt to log on using my facebook. I am asked to accept something from facebook (which I accept) and am redirected to a page (somethin with 'authentification sucess' or something in it.) This page does not load. It's not the internet as I have tried it with oth data and wifi. Not sure what to do SamsungGalaxy Captivate Glide
