I seem to be having trouble using the media player that is installed in limewire. I have enqueue'd a couple files I downloaded to the playlist, but when i press the play button in the bottom right-hand corner. Can anyone please help me? Much thanks.

Your post is a little bit confusing
What happens when you hit the play button??
Normally, if you highlight a song then enqueue it, it goes into the playlist. Press play and your playlist plays.

The LW player is not the best. It might be worthwhile making something else your default player

Cheers & Merry Xmas!

Make sure you have Continuous ticked. You can also double-click the file in the playlist to play it. See here Playlists & how to create them (click on link) It might also be a dud file. Check it's file size or play it with another player to check it's ok as birdy suggested.

Thanks guys, which default player would be a good one?

Some other decent players: 1. dBpowerAMP, - 2. WinAmp, - 3. Quintessential (QCD), - 4. iTunes (has its own music library - though depends on how you want to set it up.)

i have (5) music players in my comp. i use three regularly, for different functions. (just me i'm anal.) realplayer has been my first choice always. it's the easiest multi-purpose (that i have) to play/burn/organize/etc. i also use windows media player just because realplayer can't find older artists/albums. i use rhapsody just to put junk till i can organize it. i've never figured out i-tunes or nero. enjoying music shouldn't be hard to do.
