I am unable to install the Spotify app from mysqueezebox.com with an invalid user/password error. I do have a Spotify Premium account and my Spotify credentials are through Facebook. I've tried the following without success:
* Requesting a device id from Spotify. This results in an error from Spotify.
* Generating an app credential in Facebook and using that with either my facebook user or the actual id associated with the credential

I have installed and configured the protocol handler and the information pages indicates I am logged in.

Any help would be much appreciated.
