I have An Airport Express Connected to some speakers, And on my Iphone I can goto Airplay and choose to play the song on the Airport Express, but for some reason it never plays. I'll Hit play & it'll wait a second then jump back to Pause, When i tried to use Pandora it popped up an error message. But when i go into itunes i can play the song on my Airport Express.... It's just Airplay thats not working, Please Help. Thanks in advance.
