i'm new to limewire, and it seems that the more you share, the greater the success rate you will have with downloading. i had about 15-20 songs downloaded and in my share folder in the library, and (don't ask me why) hit "refresh". the quicktime player files are still on my HD in the Shared folder, and there are copies (and converts to mp3's) in itunes (mac OS 8.5.1), but they are no longer in my library - and thus, i do not have any files to share, nor is downloading anything successfully feasable.

how, if i can, do i retrieve the files back to the library?
and
does sharing affect dowloading success? if not, what does, is it up to the host to connect you?

thanks.
