I've gotten the first part of limewire downloaded. Now I have an icon that says 4.12.4 on it. I click on that, and go through until I get to the page that has the option of start automatically. I click on that, then it gets to a page that has something about a firewall. It has no next button or finish button or anything. I don't have a firewall and don't have a modem that would have an automatic firewall. What do I do to get past this page?
