please try including as much information as possible, so that you can get help much faster.

have you run the telnet test, to see if you have access to the Gnutella network: http://www.limewire.com/index.jsp/faqs#sta3

are you connected to the Internet before you launch LimeWire?

have you tried selecting File-Connect?

are you behind a firewall, router, or proxy server?

are you connecting from work, home, or school?

which operating system are you running? some operating systems have built-in firewalls, which you may have to configure so that Gnutella access is not blocked.
