Here, I take the plunge:
I was doing a clean-up of my PC and apparently unistalled sth I recall to be Sound Max (I'm not entirely sure); restarting the PC and trying to play music, I get the message:
"Windows Media Player cannot play the file because there is a problem with your sound device. There might be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly."
I'm using Windows XP. Can anyone please help me?
