I'm on Android, using Stalker. Mine likes to give me an authorization failed message on most streams, although Music and others open right up. In any case, after running the above that open easily, I find that I eventually can use the other streams. Weird, but true. So, you may want to try that as a work around for now.
Also on NFPS by the way. Guess I should have tried Rocket or other this time around; but you don't know until you've donated and NFPS worked OK for me last year....
Wonder if you can switch your donation over?
