I did NOT reinstall everything, I just opened limewire for the first time in months. Now, I can't connect, it says I am behind a firewall when I am not. All of the fixes are aimed at WIndows users and us mac users don't have the options to fix the problem. I have Comcast not Cox. I keep putting 6346 inot the port and LW auto changes it after restart. I just paid to upgrade and can't connect...not very fair.PLEASE post a work around for Mac users. Apparantly, Comcast is also now blocking connection to lime wire. They did an update 3 days ago ( I know b/c I lost connection for 5 min and my hubby's PC no longer connects since then) and probably added a firewall on their end that day.
