I just purchased LimeWire Pro and LimeWire will not stay connected to Gnutella. Sometimes LimeWire little light on the bottom left of the screen is red and sometimes it is green with the note that I am sharing all my files. In fact that is what is happening now.
1. The bar on the top of the screen reads
'LimeWire running the Gnutella network(Discon- nected/No files available).'
2. The button on the bottom left is green and is indicating I am sharing my files.
3. When I click on the 'Connections' icon it is showing I have 4 active connections 2 are incoming and 2 are outgoing. All 4 of the connectins read in the Vendor colum as 'LimeWire@versio...' and then there is no more room on the screen.
I bought LimeWire Pro because I thought I would get better performance.
I believe this is a LimeWire problem and not a Gnutella or firewall problem.
I have tried and tried to change my settings but nothing works!! PLEASE PLEASE WON'T SOMEBODY HELP ME?!!

Well,
The most important (and maybe only, i dont know) change in LW Pro is that it has no ads.

Wont stay connected means that all hosts your LW is trying to connect to dont accept incoming connections. Go to your connections tab and check it.

The only way to solve this problem is to add more bootstraps.
Go to options and add those servers to your list (router.limewire.com should be already entered).
public.bearshare.com
connect1.gnutellanet.com
connect2.gnutellanet.com
connect3.gnutellanet.com
connect4.gnutellanet.com

This should do the trick

Try reducing your upload speed in options->uploads->basic to a value which is reasonable for your connection speed.

Try sharing less files (if you are sharing like 1000+ files, it can cause problems).

Try disabling ultrapeer capabilities in in options->speed.
