Looks good now when I installed the Microsoft redistributable for VC++ 2008.
Now I have put my login and password. Then I got to my SB3 and browsed Radio - Spotif. I can browse my playlist, search song and artists. But when I try to play, it just says trying to connect and nothing more happens.
I don't see any attempts to play something here. What player are you using - it needs to be a hardware player which supports flac (Squeezebox 2 or later)
