please help (connection problem)
 

Hey,
I have read all the threads on connection problems, but none of the methods described worked for me. When I try to connect it says that a firewall is blocking my attempt. This message, in some form , is appearing every time I try to use a file-sharing program. The problem is I don't have a firewall on my computer, never have. I am on Windows 2000. Any help with this would be GREATLY appreciated. Thanks

p.s.
This only started to happen recently. I have been using limewire for a long time.
