limewire deletes my music! :/

[fhkmd15]

Lately, and I've used limewire for years now, but just starting a few weeks ago, I noticed my music is somehow deleting itself. nobody in my house is doing it so it has to be the computer. it deletes random songs out of my library and therefore is deleted off itunes also. a little exclamation point comes up saying file missing and I check in Limewire Library and its gone. I really can't figure this out and its getting frustrating and annoying. I have to keep redownloading music just to have it deleted AGAIN! anyone experience this?
