I have Windows Vista and I am unable to launch yahoo music gives me an error 14 were sorry, the player encountered an error streaming your music.. Any ideas?
streaming proxy settings
protocol proxy
http browser
rtsp none

i use yahoo music on my messenger.
if thats is what ur talking about...
it works for me.
i use vista also.
try to change your settign and if that doesn't work just unstall and re-install the messenger.

but if your using the website its something to do with the player..
