I suspect that's the issue. Many schools now block or filter p2p sharing nowadays b/c it compromises their bandwidth which they pay a lot of money for, & it potentially represents (incorrectly) a security risk for them. Either try a different port or try a proxy connection. To try a different port, go to LW's menu bar, Tools>Options>Advances>Firewalls & chenge the listening port to one of these (try each one): 1111, 3500, 4008, 1203, 80, 20282, 10000, 443, 40475. And remembr to press apply button after any changes. Then try to re-connect via the file menu. For proxies, see A Fix for those whose ISP's block Limewire pages 1 & 2 which has a link to alternative instructions.
