I've recently run into a problem with WMP 12 being able to stream from Internet radio stations via the Windows Media Guide. I have all the protocols turned on, temporarily turned off Windows Firewall, and have autodetect set in IE Network Connections.
I can get to the Windows Media Guide and can click on the Listen button for a station. Whenever I do this, I get a dialog box that says Windows Media Player cannot find the file. If you are trying to play, burn, or sync an item that is in your library, the item might point to a file that has been moved, renamed, or deleted.
Does anyone know why this occurs and what to do about it? I can play local music and other media via WMP.
