I am having major problems connecting. This is my first time using limewire. I downloaded the program and put in the two firewall things for tcp and udp or whatever it is called. I have windows xp and I have mcafee through aol 9.0. I am not sure why in the world it will not let me connect at all. It keeps saying that it is busy connecting. I am connecting normally to the internet through ethernet access here at school. I normally connect during the summer via dial up at home though. Thanks in advance for any and all prompt help. Thanks

Your school is probably the issue. Too many schools nowadays deliberately block p2p sharing. It uses up too much bandwidth which they pay lots of money for.

A good idea to only have one firewall active since they can interfere with each other: http://www.limewire.com/english/content/firewalls.shtml
