its an orb problem. try reinstalling the software after uninstalling. something got corrupted along the way.
btw, I mean reinstalling orb not tcpmp etc.
tell me if it works, btw. I suspect that it happened suddenly and even if you change stream between wmv or pls it still won't load and you get an "error: can't play url" message. I think one of the orb updates accidentily corrupts its media streaming file.
hth,
