I'm still having the same problems, depsite deleting my LW preferences folder. I can't stay connected to any single ultrapeer for more than a few minutes.

I'm also now getting the "brick wall" firewall icon, even though I've opened the port in my router.

This is getting puzzling!

Is there anywhere I can get the old LW version from? The problem only started when I downloaded the upgrade. Unfortunately, I don't have a backup copy of the old version.
