Can't Connect to ANY Server

[daboo]

It's now been about 4 days, that I havn't been able to connect to any server. The Server list loads just fine, but when I go to connect to a server, it freezes for about 30+ secs, and then says "The connection couldn't be established!". I've tried re-installing graal, and installing it to a different directory, but it still doesn't work. Anyone else having this problem, or any suggestions?
:grrr:

EDIT: I've sorta found the problem, it was my firewall. Though I'v been using the same brand (ZoneAlarm) for over two years now, it has never stoped me from playing Graal. It's set to allow graal to connect to the internet and act as a server too, and I havn't upgraded it, or touched any settings on it in a while. Odd, anyone else with ZoneAlarm having this problem now?
