I have made all of my music files and anything downloaded available for sharing in the Limewire preferences, but in the lower corner of the limewire window it says that I am a freeloader, and in the monitor, I can see searches being run that should hit me, but the data window remains completely empty. any ideas what might be happening?

check the Library pane, and if the shared files don't show up there, use the file menu to 'Add Folder to Share." Seems like a few people are finding they are sharing less than they thought recently, but I haven't noticed a change.
