Refresh button
 

Thanks to wondering why for helping me with my zapped library. They were in my deleted files...duh! Another question: when I hit my refresh button, all of my song information turns red. Why is that? Thanks....

Red files aren't being shared. If you're sharing heaps of files, it may take a while for the page to refresh & so you could see some red files for a time.

Otherwise, right click on a file > share file. Or restart LW.
