Since reinstalling WMP11 and configuring it to be my default player for all media types it refuses to play my mp3 podcasts. These will play perfectly well on Realplayer, etc. WMP will play my mp3 music collection with no problem. Also many online radio channels will not play. On the screen it looks as if they are playing as it connects and the clock starts running but there is no sound and the pause button is greyed (blued) out. I will be very grateful for any help that you can give me.
