It sounds as though you have added a new shared folder but when you've gone back to LW's library window you haven't pressed update. To be sure, go back to LW's menu Tools-Options & Sharing. Select the new folder u wish to add to the shared list, press Apply & OK. Now go back to LW's Library window & press Refresh. Give LW a min/2 to account for all the new files. Then select the folder on the list of shared folders on the top left side of the window. If it has a small arrow beside the folder name, click this to open the folder, otherwise just click onto the folder & all items inside the folder will display to the right hand side. Now click onto any of yur mp3's & press launch. Bingo! (Make sure in your preferences you selected LW/your default audio player to play.)
