once you drag the new theme into the theme folder, go open limewire. I would recommend that you not have limewire running as you do this. Once you have the new theme in the folder and have limewire running once more, go in to the drop down menu where you select your new theme and hit "Refresh Themes". Once you do, reopen the drop down box again and you should see your new themes. Note: I downloaded a theme that did not work when it went to limewire. It just said windows theme, but wouldn't function. Also, when switching from theme to theme, the switch is not direct. If you choose a new theme it may revert to the default windows theme first. If so, just go to the drop menu and choose your theme again. Hope that helps!!
