As the previous post indicates, the improvement in search outcomes is a result of the upgraded Limewire and has nothing to do with forcing your IP. That is necessary when you have to contend with the problem of a Firewall. Equally, the fact that you are running as a leaf and not as an ultrapeer is irrelevant. It simply indicates that you do not have a surplus of bandwidth available and are not on-line long and often enough to make it worth Gnutella's effort in designating you an ultrapper. And the prompt to upgrade to Pro is a standard part of the opening routine. When you see it, since you already have Pro, just click on Later. In short, nothing you have described is a problem that we can fix. Sorry about that because we just love to help.
