Newly Added Limewire not connecting

I have limewire on my computer and it's great. Last night I installed it on my friend's brand new computer but it is not connecting. I click on the limewire icon and are taken through to the correct page etc but when I type in a search I get "Limewire is connecting and this may result on you not getting a much searches" or words to that effect (as I remember it). They have broadband connection. I followed the steps and added Gnutella to the firewall. We ended up removing the Limewire and starting again. BUT there was a problem. When I click on the "Limewire Win set up" icon it ways that the computer detects that an older version is installed and offers me a "abort, retry or ignore". We chose to ignore. When you click on te Limewire 4.8.1 icon on the desktop you are taken through the whole "English", next next next finish process. God, what a mess. How can we get out of this spiral of trouble. Please help
