My LW media player has no volume control or progress bar and will not play files. When I transferred the files to Windows Media Player, I recieve the message "The file youare attempting to play has an extension (.mp3) that does not match the file format." When I click "Yes" to play the file, i am redirected to a website I've never heard of before and am asked to download something. I don't understand any of this, and I don't know how to fix it. Can anyone help me?
