I just downloaded limewire at my new house and when I click on 'library' it only shows the imcomplete files, not the complete ones. What do I do to listen to the music I downloaded?

When you click on the library tab, it should produce a window showing both a "shared" file and an "incomplete" file in the left-hand margin. If this is the case, click on the "shared" icon and this should reveal your completed downloads. If, however, you only have an "incomplete" icon, go to Limewire Preferences and add your "shared" file to the list under the heading of Sharing (you should have the same file listed for saving and sharing if you have only a small number of files — with larger numbers of files, you may find it better to split the whole into groups of 1,000 or so depending on the storage performance characteristics of the machine and operating system you drive).
