Pt. 2: Can't connect...
I'm an experienced LW user (4 yrs?).
I have a home Dell pc (71.6 GB Total; 38.4 free space)/ Windows XP.
Just purchased LW 4.14.10 Pro today (sorry to say).
Just downloaded Java 1.5.0_09
I'm on cable/Comcast.
I'm on McAfee security/firewall (newly installed).
I passed the "simple test".
I live in the US.
I'm not sharing the connection with other computers.
Yes, a brick wall is in front of the icon.

I hope this gives you enough detail. As I said above, this problem started a week ago w/ my old LW. I look forward to getting this settled. I've wasted far too much time trying to solve this problem.
