I've downloaded some music and I want to burn to a C.D. but the problem is WMP (Window's Media Player) can't read the files. So I go to Tools>Options>Player, and click off the Limewire thing, restart my computer and try to play the files in which it shows the WMP file symbol. But WMP says this:

Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file.

I've tried Audio File converting, but that made no difference. Not to mention I went to Microsoft and downloaded the latest codec. I need to know what on earth to do. I'm stuck and need help to get me through this.
