I'm also having the same problem as the people who can't download anything, although the file starts Connecting, pauses on that for a while, then goes to Need More Sources. I haven't been able to download anything since updating to 4.12.3, they all say Need More Sources, and if you try to find more, it stays at Awaiting Sources.

I've tried deleting the Limewire preferance folder, to no avail, and that link with the test thing said the test worked.
