Share files/ need sources
 

For some reason I can no longer access files. My share file
icon now reads zero after it was around the 800 mark before.
When I try to download I just get 'need more sources'. The resume button gets me'connecting' for a second or two then back to 'need more sources'.
I have downloaded the latest version, run my registry cleaner etc etc and listed Gnutella in the firewall settings exactly as suggested by Lord of the Rings. Nothing!
The search works fine, I just cant access anything. Two weeks ago everything was working fine - and now nothing.
What has gone wrong? HELP!!
