I?m having problems with the radio the last few days (yes, I know, it?s probably just me

). It was happily playing on Windows Media Player, then, after having to download another player (Real Player) to watch some video clips, that player has taken over and knocked the WMP off its perch.
It was OK to begin with but, since yesterday, I?ve been hearing strange noises (apart from Taffy and WG) coming through on there. The noises are like someone?s barfing in the background plus gloopy and clonking noises. Not on every song, but enough to concern me.
Now I?m repeatedly getting bumped off with a message saying my server has time out and, last off, I had a message several times saying that the player couldn?t play the file. I?ve finally managed to get it working again, but it?s definitely not happy. How can I switch the player back to WMP (in Bear language, please, as I?m a total numpty when it comes to technical stuff)?
