All of a sudden I havn't been able to connect for the past 2 days.

I am on a mac.

internet connection? cable
router? yes
firewall? yes
OS version? 9.2
limewire version? 2.1.1 ( I know it's old, but I like its features better)

Do I really need to upgrade to the newest version?

I've checked the current hosts stats for the past 2 days and don't see anything on them. Does that mean there isn't any activity? Is anyone connected? If you ARE CONNECTED AND DOWNLOADING, please reply.
