Trouble playing files

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?

The LW player is known to have problems, none of us would encourage you to use it.

There's some great tips here on how to avoid some of the trash that gets circulated on the net, and ways to get rid of any that may have found it's way into your computer: http://www.gnutellaforums.com/open-d...uld-aware.html
