over 50 songs deleted
 

I have had limewire for awhile now and it has always worked great, and then last night when I got on it I realized that songs A-F were missing. And now I cannot find them anywhere. does anyone have any idea why they were erased and how i can get them back?

Well either your drive isn't working properly (which isn't surprising for an external drive.) Or you or someone else acidentally deleted the files. See these free apps PC Inspector File Recovery (click on link), & lastly this one Restoration (click on link)
