upload okay, download stuck on "NEED MORE SOURCES

[aceyacem]

Greetings-
This is my 1st post...I'll find the intro page shortly & searched & couldn't find a similar problem:
A couple days ago I wasn't able to download-only uploading worked. I uninstalled Limewire & it started working again. Wife turned computer off & on again & it's stuck on "need more sources". I looked under help & FAQ, checked my firewall, checked my Antispamware, even turned off "pop up blocker. I have Windows XP & am using an AT&T Yahoo Browser which has worked fine. We did recently have a few viruses attached to our Antispyware & their Tech Support had me download Avast! to remove them, did it, uninstalled Avast, and now Limewire's messing up. I don't know if the 2 have anything to do w/ each other. Please help! Has something changed recently on LimeWire?
