Where did you get an expiring trial version? As far as I know, the basic (read "free") version of LW does not stop function after a set amount of time...
Anyway, for information on how t disable firewalls, or rather, give LW permission to connect and stuff with the firewall
on, go to the LW web site (
www.limewire.com) and read the FAQs about firewalls. I think they're pretty understandable.
