I'm having a similar problem with a station that recently (this week) switched to StreamTheWorld from an ASX format. It is currently listed in the Media Guide, CIDC 103.5 FM Toronto, Canada, but because of the recent switch, I'm guessing the link is out of date.
The link on the station's website is http://www.z1035.com/player.php.
Link to just the Flash-based player is http://player.streamtheworld.com/liveplayer.php?callsign=CIDCFMAAC
Source on the player page is:

The URL Finder can't pick out the link to the stream, and neither can I from the HTML. Any ideas?
