That means that you have made a mistake either when configuring the Firewall or portforwarding your router. Or there is something blocking Limewire that you don't know of. Try and look at everything you have done so far to see if there is anything that you might have skipped, misread or put the wrong number in. Also download CCleaner (just use google to find it) is has much more efficient add/remove programs. If there is some other firewall then it will come up there I believe. If some programnames come up that you do not recognise then google the names to see what they are.
