No Dwnload Sources

I am absolutely sure that there is something wrong with Limewire when it tries to find sources for any particular download.

Why? Because I had a downloaded file of which I didn't find any sources for a long period of time.. a week or something. And then, by simply searching with Limewire for the same file, I see the file is being resumed to download.

This means that my manual search aided Limewire to find sources and its automatic source finding sucks.

Thanks,
