I am unable to download any files all of a sudden.

I am connected ok, have gone into search, found the files clicked on download, but after the message "CONNECTING", I then get "MORE SOURCES NEEDED".
This is happening on EVERY file that I try to download, regardless of artist / title or album.
I've been experiencing this bug / problem every day for every file for the last few days.
Is there a temporary problem / bug with LIMEWIRE?
